New Adsorbents Based on the InSb–CdSe Heterosystem. Volumetric and Surface Properties

Resumo

Based on the InSb–CdSe heterovalent substitution system, new adsorbents have been obtained being solid solutions with the structure of sphalerite and wurtzite, depending on the composition. Their crystal-chemical, structural, optical (Raman and IR spectra), electrophysical (electrical conductivity, Hall effect, energy-gap), and surface (chemical composition of surfaces, acid–base, and adsorption properties) properties have been studied. The mechanisms of surface atomic-molecular processes, regularities of changes in the studied properties, the relationship between the laws, the predictions arising from it and supported by specific results on the surface activity of system components have been established. Accordingly, practical recommendations are given to manufacture gas sensors, p-n heterotransitions, and subsequently luminescent diodes and photoelectric converters.
