Surface properties of chalcogen passivated GaAs ( 1 0 0 )

Chalcogen atoms like sulphur or selenium are promising candidates for the passivation of GaAs(1 0 0) surfaces. The passivation can be obtained by evaporation of S or Se under ultra-high vacuum (UHV) conditions or by etching in chalcogen containing solutions. In both cases, an additional annealing of the samples leads to Ga-chalcogenide like surface layers showing a 2 1 low energy electron diffr...

Drug-gene interactions: inherent variability in drug maintenance dose requirements.

The influence of genetics on pharmacokinetics can introduce variability among individual patients that may cause treatment failure, toxicity, or both. Such variability, specifically in clearance rates, can influence drug maintenance dosing regimens.

Spectroscopic and Optoelectronic Properties of Hydrogenated Amorphous Silicon-Chalcogen Alloys

Hydrogenated amorphous silicon-chalcogen alloy thin films have been the subject of growing interest during the past two decades. Thin films of these alloys are usually prepared by the decomposition of SiH4 and H2S or H2Se gas mixtures in a radiofrequency plasma glow discharge at a substrate temperature of 250°C. The alloy composition is varied by changing the gas volume ratio RV = [chalcogen/ s...

Optical properties of chalcogen-loaded zeolite (ZSM-5)

Sulfur, selenium, and tellurium were loaded into sub-mm size ZSM-5 single crystals and the optical properties have been comparatively studied. S and Te show similar features, while Se is unique. S and Te have optical absorption edges at wavelengths of ~400 nm with transmission dips at ~450 nm, while Se has the edge at ~550 nm. The three materials provide photoluminescence at visible wavelengths...
