Bulk and Surface Properties of ZnTe-ZnS System Semiconductors

Physicochemical studies of a new ZnTe-ZnS semiconductor system are conducted. It is found that at certain ratios of binary components, substitutional solid solutions with a cubic sphalerite structure are formed in this system. Interrelated laws governing changes in the bulk ( crystal chemical, structural) and surface ( acid-base) properties with varying system composition are identified. It is assumed they can be attributed to the nature of the active ( acid-base) sites. The presented data, observed patterns, and an interpretation of them are used not only to confirm earlier proposed mechanisms of atomic-molecular interaction on diamond-like semiconductors, but to search for promising materials for use in highly sensitive selective sensors for environmental and medical purposes as well.
