Chromium oxide (α-Cr2O3) thin films were prepared using thermal annealing of chromium (Cr)films deposited on quartz substrates by direct current (DC) magnetron sputtering. The annealingprocess of the films was performed for different times of 60, 120,180 and 240 min. The influenceof annealing time on structural, morphological and optical properties of the prepared films wasinvestigated by diffe...

We report here the effect of thermal annealing on the thermal conductivity of ZnTe nanowires measured on a microfabricated suspended device. Molecular dynamics simulation was used to calculate the effect of contacts on the measurements at different temperatures and to estimate the intrinsic nanowire thermal conductivity values. A decrease in thermal conductivity was observed after each thermal ...

The luminescence properties of inorganic perovskite CsPbBr3 nanocrystals (NCs) with emissions of 492 and 517 nm under thermal annealing treatment were studied by temperature-dependent photoluminescence (PL) spectroscopy. The CsPbBr3 NCs were annealed in vacuum at various temperatures. It was found that the NCs exhibited significant thermal degradation of PL at thermal annealing temperatures abo...

InN films grown by molecular beam epitaxy have been subjected to 2 MeV He + irradiation followed by thermal annealing. Theoretical analysis of the electron mobilities shows that thermal annealing removes triply charged donor defects, creating films with electron mobilities approaching those predicted for uncompensated, singly charged donors. Optimum thermal annealing of irradiated InN can be us...

We study thermal annealing effects on the size and composition variations of indium-aggregated clusters in two InGaN thin films with photoluminescence ͑PL͒ in the yellow and red ranges. The methods of investigation include optical measurement, nanoscale material analysis, and theoretical calculation. Such a study is important for determining the relation between the band gap and the average indiu...

We investigate a new method (QTA-PIMC) for global optimization on complex potential energy surfaces which combines the path integral Monte Carlo method with quantum and thermal annealing. This method is applied to the BLN protein model (Honeycutt, J. D.; Thirumalai, D. Biopolymers 1992, 32, 695). We show that this new approach outperforms simulated (thermal) annealing (SA) and that in fact SA i...

Titanium oxide coatings have been deposited by the sol-gel dip-coating method. Crystallization of titanium oxide coatings was then achieved through thermal annealing at temperatures above 400 °C. The structural properties and surface morphology of the crystallized coatings were studied by micro-Raman spectroscopy and atomic force microscopy, respectively. Characterization technique, based on le...

Wong’s diffusion network is a stochastic, zero-input Hopfield network [8] with a Gibbs stationary distribution over a bounded, connected continuum [13]. Previously, logarithmic thermal annealing was demonstrated for the diffusion network [10], [7] and digital versions of it were studied and applied to imaging [14]. Recently, “quantum” annealed Markov chains have garnered significant attention [...

We investigate the electrical properties of polycrystalline silicon thin films implanted with arsenic or boron ions. Two types of post-implantation annealing have been performed on the samples a conventional thermal annealing (CTA) and a rapid thermal annealing (RTA). We find that RTA improves the electrical properties. Measurements of gauge factors have been carried out on both films. We concl...

Both high brightness and high efficiency of polymer light-emitting diodes can be obtained by electrical annealing after an appropriate thermal treatment. Light-emitting diodes made of poly @2-methoxy-5-~28-ethyl-hexyloxy!-1,4-phenylene vinylene# ~MEH-PPV! with an Al electrode were used for this study. Thermal annealing after Al deposition dramatically enhanced the luminous efficiency of electro...
