The alloy scattering potential is an important parameter in SiGe alloys since it not only affects the velocity-field characteristics for carrier transport, but also allows increased optical transitions by relaxing k-selection rules. In this letter, we report on the velocity-field measurements for relaxed and coherently strained SiGe alloys. The alloy scattering potential is obtained from a care...

We report that the oxygen binding energy of alloy-core@Pt nanoparticles can be linearly tuned by varying the alloy-core composition. Using this tuning mechanism, we are able to predict optimal compositions for different alloy-core@Pt nanoparticles. Subsequent electrochemical measurements of ORR activities of AuPd@Pt dendrimer-encapsulated nanoparticles (DENs) are in a good agreement with the th...

The electrocatalytic properties for electro-oxidation reactions of shape-controlled Pt-based catalysts have been improved by alloying with 2nd elements. In this study, we demonstrate cubic PtPd alloy nanoparticles synthesized using a thermal decomposition method. The cubic PtPd nanoparticles exhibit a homogeneous distribution of alloy nanostructures in the presence of Pt and Pd metallic phases....

The metals for porcelain fusing used in this study were gold alloys and nickel-chromium alloys. Chromatic characteristics were compared between samples of 0.1, 0.2 and 0.3 mm thickness. The dentin porcelain was fused on the opaque surface. Chromatic analyses were then carried out at each stage of 0.1 mm-incremental reductions of the dentin thickness starting from 0.5 mm. In conclusion, the meta...

The Ni60Nb15Ti15Zr10 glassy alloy was developed as a separator material for a proton exchange membrane fuel cell (PEMFC). The corrosion rate of the glassy alloy in sulfuric acid was approximately 3 digits lower than SUS316L. A precise groove forming of the glassy alloy can be achieved by hot-pressing in the supercooled liquid state. The result of the power generation test of the single cell ass...

The dilute bismide semiconductor GaAs1-xBix represents an interesting counterpart of the dilute nitride alloy GaAs1-xNx. Both exhibit giant bandgap bowing phenomena but with oppositely directed effects on the valence and conduction bands respectively. The optical properties of the dilute bismide alloy will be contrasted with those of the dilute nitride and the similarities and distinctions betw...

Using atomically and momentum resolved scanning tunneling microscopy and spectroscopy, we demonstrate that a two-dimensional (2D) √3 × √3 semiconducting Ga-Si single atomic alloy layer exhibits an electronic structure with atomic localization and which is different at the Si and Ga atom sites. No indication of an interaction or an electronic intermixing and formation of a new alloy band structu...
