Surface properties of semiconductor analogs of CdBVI and their solid substitution solutions

Abstract

The physicochemical (acidic-basic, adsorption, and electrophysical) surface properties of binary semiconductor analogs of CdB^VI (CdTe, CdSe, and CdS), and (CdTe)_x(CdSe)_1–x, and (CdTe)_x(CdS)_1–x solid substitution solutions were studied using modern methods and equipment. The nature of the active centers and the mechanisms of acidic-basic, adsorption (involving СО), and electronic interactions, interrelated tendencies in variation of the surface properties under study, and their correlations with the known bulk physicochemical properties were elucidated; the property–composition diagrams were constructed, which were used to reveal the most active adsorbents suggested for use as materials for СО (carbon monoxide) microimpurity sensors.
