The fluorine redistribution during partial solid-phase-epitaxial-regrowth at 650 °C of a preamorphized Si substrate implanted by F was investigated by atom probe tomography (APT), transmission electron microscopy, and secondary ions mass spectrometry. Three-dimensional spatial distribution of F obtained by APT provide…
Low temperature micro-photoluminecence and second-order single photon correlation experiments were performed on individual self-assembled In0.47Al0.34Ga0.19As/Al0.3Ga0.7As/GaAs quantum dots emitting in the range of 680–780 nm. Emission lines originating from exciton, biexciton, and charge exciton confined in the same…
We report a classical model on the size effect of the electron wind force on a metal atom at the metal-dielectric interface in nanoscale interconnects. The effect is expressed as a size factor S for the effective charge Z*e. It is found that the size factor decreases with scaling due to reduced electron drift momentum…

Sum Frequency Generation (SFG) spectra of monolayer films on metal surfaces have been simulated where the monolayer contains methyl groups in two different orientations. The two methyl group tilt angles were taken into account by including a second resonant term in the expression for the second-order non-linear suscep…
The paper presents an experimental investigation into the internal blast loading of open-ended, seamless, mild steel cylinders. A series of 10 trials were conducted on explosively loaded vessels using increasing masses of PE4 explosive. The objective of these trials was to determine the maximum circumferential strain…
Graphitic nanoplatelets (GNPs) and luminescent carbon nanoparticles (CNPs) are simultaneously synthesized by controlling the laser parameters and the size of the graphite flakes. Because luminescent CNPs are attached onto GNPs, a new carbon nanostructure is obtained. Compared with carbon black, GNPs, and luminescent C…
The photoemission cross-section of the Shockley surface state of Au(111) is studied over a wide range of photon energies both experimentally and theoretically. The measurements are fully understood based on the theoretical analysis within a one-step ab initio theory of photoemission. The constant initial state spectru…
The efficiency decrease during electrical operation of organic light-emitting diodes is a crucial issue for both applied and fundamental research. In order to investigate degradation processes, we have performed an efficiency analysis for phosphorescent state-of-the-art devices in the pristine state and after an accel…
The changes in the atomic and electronic structure of Si- and C-terminated hexagonal SiC{0001} surfaces resulting from on-surface and subsurface hydrogen adsorption have been studied within the density functional theory framework. Hydrogen coverages ranging from a submonolayer to one monolayer were considered. Our res…
We attempted to fabricate the oriented bulk LiCoO 2 using slip casting in a strong magnetic field. The shrinkage of the oriented green compact was measured using a dilatometer. It was confirmed that the oriented green compact undergoes anisotropic shrinkage. The shrinkage in the c‐ plane direction of the oriented LiCo…
The isotopic phonon effects in LaB(6) are investigated on the Raman spectra of a series of high-quality single crystals with systematically varied contents of (10)B and (11)B isotopes. A detailed group theoretical analysis enlightens the correlation between distortions of the B(6) octahedra and the splitting or broade…
The chalcopyrite semiconductors show large tolerances to deviations from stoichiometry by keeping the crystal structure. Such deviations always cause structural inhomogeneities and charge mismatches which influence the material properties. We studied the type and concentration of cationic point defects on Cu-poor CuGa…
The full elastic tensor of orthorhombic dysprosium scandate (DyScO(3)) at room temperature was determined by resonant ultrasound spectroscopy (RUS). Measurements were performed on three 500 μm thick substrates with orientations (110), (100) and (001) in the Pbnm (a < b < c) setting. For this purpose, a modification of…
We have studied the effect of amphiphilic polymers with different structure (polyvinylpyrrolidone, polyethyleneoxide and a triblock copolymer of ethylene- and propyleneoxide—(Pluronic F127)) on the photoactivity of a hematoporphyrin derivative (dimegin). It has been shown that such polymers can cause a considerable in…
An advanced model of irreversible thermoelectric generator with a generalized heat transfer law is established based on finite time thermodynamics. The generalized heat transfer law represents a class of heat transfer laws including Newtonian heat transfer law, linear phenomenological heat transfer law, radiative heat…

The kinetics for the termination migration of a rod-type alpha particle in a two-phase Ti alloy was predicted on the basis of the edge recession theory. The developed model quantified the effect of geometrical dimensions and diffusional factors on the spheroidization rate. Comparison with the experimental results of T…
Analysis of dielectric barrier discharge microplasma at atmospheric pressure was carried out using emission spectroscopy and imaging techniques. Temporal evolution of the discharge and also its filamentary mode was observed for the discharge in 3% N2 in Ar at the microdischarge level. Light emission from microplasma o…
We show that pure rutile TiO(2) can be photo-responsive even under low energy visible light after annealing in vacuum where we envisage that the point defects, i.e. oxygen vacancies and titanium interstitials, serve an important role. In this study, single crystal rutile films were grown by the pulsed laser deposition…
