Abstract
Section titled “Abstract”Methods for the preparation of GaAs-CdSe and ZnTe-CdSe solid solutions based on isothermal diffusion of the initial binary compounds (GaAs and CdSe, ZnTe and CdSe) with their main bulk physical and physicochemical properties taken into account are developed. X-ray, microscopic, electron-microscopic, and spectroscopic data enriched the database on multicomponent diamond-like semiconductors. They include the luminescence properties, average sizes, and average numbers of particles. This makes it possible to unambiguously certify solid solutions as of the substitutional type with a cubic sphalerite and wurtzite hexagonal structures depending on the composition. The surface properties (chemical composition and acid-base properties) of the solid solutions and binary components of the systems are studied. When the surfaces are predominantly weakly acidic, there is a relative increase in the basicity with an increase in the amount of CdSe and ZnTe in the GaAs-CdSe and ZnTe-CdSe systems, respectively. The changes in the composition of bulk and surface properties and the correlations between them are found. This simplifies the search for new materials—the primary transducers of sensors.
