In the current investigation, various mass fractions (0, 0.5, 1.5, 5 and 10 wt%) of Ni were doped into Cu substrate, and influences of Ni addition on the microstructure evolution and mechanical property of the Sn–58Bi/Cu–xNi solder joint were investigated. Results showed that the growth rate of intermetallic compound (IMC) would increase with the Ni addition added from 0 to 5 wt% and remarkably decreased for Sn–58Bi/Cu–10Ni joint system. It indicated that the growth rate of IMC layer would decrease when 10 wt% Ni was added into the alloy. Besides, the tensile strength reduced with increase in the IMC thickness, which was under the synergistic effect of increasing liquid-state reaction time and the content of Ni addition (0–5 wt%). Moreover, the fracture mechanism gradually transformed from ductile fracture mode to brittle fracture mode with the decrease in joint strength.

Durango apatite was irradiated with energetic U ions of 2.64 GeV and Kr ions of 2.1 GeV, with and without simultaneous exposure to a pressure of 10.5 GPa. Analysis by confocal Raman spectroscopy gives evidence of vibrational changes being marginal for fluences below 5×1011 ions/cm2 but becoming dominant when increasing the fluence to 8×1012 ions/cm2. Samples irradiated with U ions experience severe strain resulting in crystal cracking and finally breakage at high fluences. These radiation effects are directly linked to the formation of amorphous tracks and the fraction of amorphized material increasing with fluence. Raman spectroscopy of pressurized irradiated samples shows small shifts of the band positions with decreasing pressure but without a significant change of the Grüneisen parameter. Compared to irradiations at ambient conditions, the Raman spectra of apatite irradiated at 10.5 GPa exhibit fewer modifications, suggesting a higher radiation stability of the lattice by the pressure applied.

Searching for novel two-dimensional (2D) materials based nanoscale electronic devices is a hot topic in the current research. A modulation of materials’ specific physical properties by altering external conditions has long been used. There are a variety of routes to improve the specific behavior of materials. In this paper, the structural, electronic, and the corresponding variational characteristics of the graphene(g)-MoTe2/WTe2 heterointerfaces are studied in detail based on ab initio calculations with nonlocal van der Waals (vdW) corrections. We performed research on the band alignments of g–MoTe2/WTe2 contacts and a concise routine to reduce the Schottky barrier and obtain Ohmic contact. The results predict a barrier height of 62 meV and 280 meV for g–MoTe2/WTe2, respectively, in a neutral state. In the applied electric field, the corresponding Schottky barriers can be effectively tuned by various electric fields. The height of the barrier further decreases to 0 under − 0.02/0.16 V/Å and − 0.06/0.08 V/Å for g–MoTe2/WTe2, respectively, and the numerical value of the barrier and the corresponding Schottky type can be regulated in a flexible way. Additionally, theoretical calculation results also demonstrate that g–MoTe2 has a smaller Fermi level pinning effect than g–WTe2, which plays a significant role in the fabrication of novel transistors based 2D materials and it should be a better choice for FETs application.

A Spectroscopic study has been made of the emission spectra arising from ArF laser initiated photoablation of PMMA samples. This process leads to direct etching of the polymer. The thermal temperature of the CH fragment species in the plume immediately above the ablated site was found to be ∼ 3200 ±200 K. The translational velocity of this species was found to be ∼4.2×105 cm/s corresponding to a translational temperature of ∼ 11,000 K. These results are consistent with a rapid direct bond scission model for ablation.

An efficient emission of picosecond bunches of energetic protons and carbon ions from a thin layer spalled from a organic solid by a laser prepulse is demonstrated numerically. We combine the molecular dynamics technique and multi-component collisional particle-in-cell method with plasma ionization to simulate the laser spallation and ejection of a thin (∼20–30 nm) solid layer from an organic target and its further interaction with an intense femtosecond laser pulse. In spite of its small thickness, a layer produced by laser spallation efficiently absorbs ultrashort laser pulses with the generation of hot electrons that convert their energy to ion energy. The efficiency of the conversion of the laser energy to ions can be as high as 20%, and 10% to MeV ions. A transient electrostatic field created between the layer and surface of the target is up to 10 GV/cm.

Positron lifetime measurements have been performed inn-type andp-type germanium single crystals deformed by compression. The results are compared with those of deformed GaAs single crystals obtained by the authors previously. In bothn andp-type germanium the lifetime τ1 and its intensityI 1 decreased with deformation. Using the trapping model, the trapping rates of positrons by dislocations are obtained, which in turn gave the cross width of the dislocation as 20.0 Å and 8.2 Å forn-type andp-type germanium, respectively. In terms of Reads model the fraction of the dangling bonds occupied by electrons is obtained to 0.26 in then-type germanium. This value was smaller than those obtained forn-type GaAs, i.e., 0.46 and 0.50 for Ga- and As-dislocation, respectively. It is found that doping causes the trapping of positrons. Inp-type germanium the fractionf was determined to 0.25 in terms of Schröter and Labuschs model.

Özet Ek Bilgiler

Laser induced damage thresholds of a bandpass filter with TiO2/SiO2 coatings are measured, with the laser delivering wavelength tunable, high-repetition rate, and ultrashort pulses. The multiple wavelengths are selected within the transitional region between the filter passband and stopband. A method that scans the sample along the focused laser beam is employed to vary the spot size on the coating and, consequently, change the fluence. The damage is detected by both a CCD camera and by monitoring the transmitted power simultaneously. During the experiment, an increase in the filter transmission was observed prior to damage occurrence. We demonstrate that damage induced on the coating by the high repetition rate, femtosecond pulses is governed by macroscopic thermal behavior rather than by critical free electron density in the conduction band. In addition, the process of energy deposition is determined by intrinsic nature of the coating materials. Further analysis indicates that the thresholds as a function of wavelength are determined by the combination of the properties of TiO2, interference field in the coating stack, and thermal effects. Moreover, we attribute the observed increase in the coating transmission to these thermal effects rather than ionization processes.

Ferroelectric Bi3.25La0.75Ti3O12 (BLT) thin films have been grown on Pt/Ti/SiO2/Si substrates by chemical solution methods. X-ray diffraction analysis shows that BLT thin films are polycrystalline with (171)-preferential orientation. Atomic force microscopy investigation shows that they have large grains about 120 nm in size. A Pt/BLT/Pt capacitor has been fabricated and showed excellent ferroelectricity, with a remnant polarization and coercive field of 24 μC/cm2 and 116 kV/cm, respectively. The capacitor shows no polarization fatigue up to 109 switching cycles. The optical constants (n,k) of the BLT thin films in the wavelength range 0.35–1.7 μm were obtained by spectroscopic ellipsometry measurements, and the band-gap energy was found to be about 3.25 eV.

Electronic transport properties of mechanically alloyed phosphorous-doped SiGe alloys at low temperatures were examined. We found that in this granular medium hopping-processes show an influence on the electronic conductivity. In addition, Hall-measurements revealed that the electron mobility reflects the band-structure of this alloy concerning intervalley-scattering and alloy-scattering. Mobility reaches a minimum at an alloy composition of roughly 25 at.% silicon.

Özet Ek Bilgiler

A novel effect is studied of self-limitation of the diamond-like film thickness during laser irradiation of the interface of transparent substrates with liquid aromatic hydrocarbons. The interface is exposed through the transparent substrate to radiation of a copper vapor laser (wavelength of 510.6 nm, pulse duration of 20 ns). The thickness of diamond-like film increases linearly to 80–100 nm with the number of laser pulses and then saturates, while the substrate is ablated with nearly constant rate. This ablation rate depends on the thermal expansion coefficient of the substrate (glass, fused silica, sapphire, or CaF2). The absorption of extinction coefficient of deposited films measured by ellipsometry is of order of 104 cm-1 and is sufficient to cause the significant heating of the interface. The ablation of the transparent substrates is due to their unequal thermal expansion compared to the diamond-like film having different thermal expansion coefficient. The measured ablation rates scale from 0.2 Å/pulse for glass to 4.5 Å/pulse for CaF2. A μm spatial resolution of the ablation process has been demonstrated for fused silica.

The saturation of the fundamental harmonic of the space-charge field is investigated experimentally in dependence of the contrast m and the amplitude of an external ac and dc field in a BTO crystal with a large electron-drift length. The behaviour of the first harmonic is explained qualitatively with the aid of perturbative analysis.

We present a combined experimental and theoretical study to investigate the spatial distribution of photoelectrons emitted from silver-coated polystyrene nanoparticles. We use two-photon photoemission electron microscopy (2P-PEEM) to image electron emission from a silver-capped aggregate trimer. Finite difference time domain (FDTD) simulations are performed to model the intensity distributions of the electromagnetic near fields resulting from femtosecond laser excitation of localized surface plasmon oscillations in the trimer structure. We demonstrate that the predicted FDTD near-field intensity distribution reproduces the 2P-PEEM photoemission pattern.

Materials showing reversible resistance switching at room temperature are attractive for today’s semiconductor technology with its wide interest in nonvolatile random access memories. In this letter, the switching between the high resistance state (OFF-state) and the low resistance state (ON-state) was demonstrated, which depends on both polarity and magnitude of the applied electric pulse. Such a phenomenon could be useful for various magnetic and electric device applications. A “conductance channel” model is proposed to explain the observed effect. This mechanism is supported by the experimental data obtained from the multi-resistance states measured synchronously.

The electrical properties and preferred lattice site of Cu in GaAs were investigated combining electrical and optical measurements with ion beam and structural analysis. From this comprehensive study it was determined that Cu introduces two levels in the band gap, that the concentration of electrically active centers introduced by Cu diffusion is considerably smaller than the total Cu concentration, that this ratio of electrically active to total Cu concentration depends strongly on the cooling speed after diffusion, and that the portion of Cu that remains electrically inactive forms Cu-Ga precipitates.

We present a study of the temperature non-homogeneities induced by millisecond laser annealing in advanced CMOS technologies at die level. Because of the design, the device layout at the wafer surface introduces during this anneal significant spatial variations of optical absorption and heat transfer that can induce temperature non-uniformities over the die, often called ‘pattern effects’. These temperature variations are becoming a major issue, since they are the origin of significant device properties dispersion. A complete optical and thermal simulation set has been developed to estimate the temperature variations induced by the topologies at the wafer surface during the laser anneal process. The modelling has been validated by either a comparison with another software or reflectometry and electrical measurements on real structures. This work demonstrates that the temperature variations are caused either by optical coupling or by thermal properties dispersion present at the wafer surface at the anneal step. Finally, we demonstrate that the impact of the thin-film interferences and diffraction phenomena is the critical issue for these pattern effects.

Three types of ZnO-based nanocomposites were fabricated consisting of 80-nm Au nanoparticles (NPs), a graphene layer, and ZnO nanorods (NRs). To investigate interactions between the ZnO NRs and Au nanoparticle, multiple material analysis techniques including field-emission scanning electron microscopy (FESEM), surface contact angle measurements, secondary ion mass spectrometry (SIMS), X-ray photoelectron spectroscopy (XPS), and Raman spectroscopic characterizations were performed. Results indicate that incorporating a graphene layer could block the interaction between the ZnO NRs and the Au NPs. Furthermore, the Raman signal of the Au NPs could be enhanced by inserting a graphene layer on top of the ZnO NRs. Investigation of these graphene-incorporated nanocomposites would be helpful to future studies of the physical properties and Raman analysis of the ZnO-based nanostructure design.

The recent development of the problem of coexistence of magnetism and superconductivity will be reviewed. The possible coexistence of superconductivity with various types of magnetism carried by localized magnetic moments and itinerant electrons is critically discussed in connection with several existing materials such as rare earth ternary compounds [(RE)Mo6S8, (RE)Mo6Se8 and (RE)Rh4B4], newly synthesized organic superconductors [(TMTSF)2X] and Y9Co7. In order to obtain a coherent picture for the understanding the rich phenomena associated with the interplay between two mutually exclusive types of long-range order, a unified point of view based on a key concept of the partial gapping model proposed by the author is introduced as a working hypothesis.

Laser chemical vapor deposition of copper has been performed under a variety of conditions. The results are interpreted using the kinetic model of Ehrlich and Tsao. We find that the kinetics of the process are limited by the rates of surface reactions and not by diffusion of reactant molecules to the surface. Furthermore, we find that deposit shapes are quite sensitive to laser intensity and scan rate.

Beeswax coatings applied to seal off the granitic surfaces of many monuments have resulted in detrimental effects with time passing. Conservation procedures must be carried out in a selective way, removing the beeswax without any degradation of the stone. In this study we present an experimental analysis of the removal of beeswax using a Nd:YAG laser at a wavelength of 355 nm which is absorbed weakly by the beeswax. For this reason, an important percentage of the laser radiation reaches the granite substrate and the influence of the layer thickness must be studied. At each laser fluence, for single-pulse irradiation we find a maximum thickness for complete removal of the film. For thicker layers, the beeswax is not removed and additional effects such as color changes and thickness increase are observed. The experimental results suggest that a photomechanical mechanism is dominant and that granite absorption plays a fundamental role. Multiple-pulse irradiation is also performed to determine the optimal parameters for laser cleaning. Finally, infrared thermography measurements allow for the determination of the granite surface temperature after laser irradiation and theoretical calculations allow one to estimate the absorption behavior of granite at 355 and to explain the results obtained.

We aim to reveal the influence of pH values of the working solution on spatial arrangement of metal-containing inclusions in the monolayer coatings prepared by Langmuir–Blodgett (LB) technology and transferred to solid substrates with consequent modification of surface electrical properties. Consequently, films with inclusions in the form of dendrites and cluster shapes have been obtained. Submicron and micron lead-containing formations in Langmuir–Blodgett films have been characterized by using the atomic force microscopy, Kelvin probe microscopy, and scanning electron microscopy methods. The results show that increasing pH value of the subphase has caused the significant changes in the shape and composition of the inclusions in Langmuir–Blodgett films. The synthesized inclusions on the solid substrate surface resulted in formation of the regions with the local electric fields and, as consequence, to significant modification of the structure and electrical properties. The location and length of the regions with surface potential disturbance depend on the shape of inclusions, and consequently, on pH value of the subphase used in LB technology.

/cm3. After this new ECD treatment, PS:Er was found to emit much more intense room-temperature visible photoluminescence than both the porous silicon control and the PS:Er prepared by constant-current ECD. Room-temperature IR photoluminescence around 1.54 μm was observed for the first time without any post-doping annealing.

We experimentally investigate the effect of post-deposition annealing on the charge distribution of a metal-oxide-semiconductor capacitor with a TiN/HfO2/SiO2/Si gate structure. We decoupled interfacial charges at the SiO2/Si and HfO2/SiO2 interfaces; bulk charges in HfO2; and the dipole formation at the HfO2/SiO2 interface. The interfacial charges at the HfO2/SiO2 interface decreased and the dipole increased after H2 or N2 annealing. Oxygen dangling bonds are the physical origin of the charges at the HfO2/SiO2 interface. The interfacial charges at the SiO2/Si interface and the bulk charges in HfO2 are almost unchanged.

ZnO nanorods were coated with TiO2 thin film using the atomic layer deposition (ALD) process. X-ray diffraction, scanning electron microscopy, and transmission electron microscopy were used to characterize the crystal structure and surface morphology of the coated composites. Results of galvanostatic charge and discharge tests and cyclic voltammograms suggest that lithium ions can reversibly intercalate into and deintercalate from TiO2-coated ZnO nanorods, and that stable cycling behavior in an ethylene carbonate-based electrolyte can be achieved. The TiO2 coating is believed to reduce the degree of reaction electrodes have with the electrolyte during the charge–discharge process since the inactive coating layer prevents the electrode from having direct contact with the electrolyte. Furthermore, the one-dimensional nanorods provide a relatively higher surface area than those of their bulk form or thin film, which allows a much greater portion of atoms on the surface to undergo the electrochemical reaction. The electrochemical study indicates that the TiO2-coated ZnO nanorod arrays might be a candidate for the anode material in Li-ion batteries.

We consider cooling of a trapped particle in the limit when the position and velocity variables do not change adiabatically. The slowly varying quantity in a harmonic trap is then the energy, and a representation based on oscillator eigenstates is used. For large excitation, fast particles, a Fokker-Planck expansion is obtained which is valid when our adiabatic description breaks down. Estimates of the initial cooling rate are given and compared with earlier results. Our treatment requires a large number of oscillator states to be coupled by each one-photon process, and in this limit the diffusion will make the expansion invalid towards the end of the cooling; our physical interpretation is that particles leak out of the trap. The opposite case, the Lamb-Dicke regime, is advantageous for cooling experiments, and then a difference equation replaces the Fokker-Planck equation of the present paper.

By solving the time-dependent heat flow equation, the temperature reached by silicon and cadmium telluride surface layers under high power density ruby laser pulsed illumination, is calculated. The results are presented in directly useful figures allowing the determination of the surface temperature, its evolution towards the bulk as a function of time... In particular, it should be noticed that for a 25 ns half-power width, pulses of 0.8J/cm2 are sufficient to melt the top of an amorphous silicon layer, this value becomes noticeably lower for cadmium telluride.

A novel graphene-based material of tea saponin functionalized reduced graphene oxide (TS-RGO) was synthesized via a facil thermal method, and it was characterized as the absorbent for Cd(II) removal from aqueous solutions. The factors on adsorption process including solution pH, contact time, initial concentration of Cd(II) and background electrolyte cations were studied to optimize the conditions for maximum adsorption at room temperature. The results indicated that Cd(II) adsorption was strongly dependent on pH and could be strongly affected by background electrolytes and ionic strength. The optimal pH and required equilibrium time was 6.0 and 10 min, respectively. The Cd(II) removal decreased with the presence of background electrolyte cations (Na+ < Ca2+ < Al3+). The adsorption kinetics of Cd(II) followed well with the pseudo-second-order model. The adsorption isotherm fitted well to the Langmuir model, indicating that the adsorption was a monolayer adsorption process occurred on the homogeneous surfaces of TS-RGO. The maximum monolayer adsorption capacity was 127 mg/g at 313 K and pH 6.0. Therefore, the TS-RGO was considered to be a cost-effective and promising material for the removal of Cd(II) from wastewater.
