Popis: Based on analysis and generalization of the results of studies of the surface (acid-base and adsorption) properties of components of the GaSb–ZnTe system, the regularities of their changes with varying composition are established; it is found that they may both obey Vegard’s rule (exhibit a smooth character) and deviate from it (exhibit an extreme character). The reasons for the appearance of extrema in the property–composition diagrams are explained. Correlations between the surface and bulk properties are found, which are useful not only in scientific but also in practical aspects. The absorbents that are the most active with respect to NH3, CO, and O2 are identified; it is proposed to use them for manufacturing corresponding sensors. The possibility and feasibility of using the results obtained for semiconductor gas analysis are shown.
