Thermal oxidation of gallium arsenide with transition metal nanolayers on the surface

Abstract

The physicochemical features of the interaction between nanofilms of iron triad metals and the gallium arsenide surface during thermal oxidation are analyzed. The role of oxides formed upon oxidation of iron, cobalt, and nickel metal films in the course of thermal oxidation of gallium arsenide is demonstrated, and the influence of the metal deposition method on the kinetics of oxidation, the composition, and the properties of the prepared samples is determined. Schemes are proposed for the development of the oxidation processes under investigation with due regard for the chemical specific features of the iron triad metals and their compounds.

From Small Metal Clusters to Molecular Nanoarchitectures with a Core–Shell Structure: The Synthesis, Redox Fingerprint, Theoretical Analysis, and Solid-State Structure of [Co38As12(CO)50]4–

“…The design of molecular architectures with different structural elements is relevant for synthetic purposes since the formation of strong bonds between metal and main group atoms may confer extra stability . Additionally, this class of compounds has been used as a single source for binary and ternary phases which, in turn, can find application as semiconductors or magnetic nanoparticles (NPs) for the deposition of thin films, for catalysis, and for electrocatalysis . In the field of semiconductors, core–shell structures have attracted considerable interest since the outer shell can modify the properties of the inner one, extending the spectrum of applications .…”
