Comparative Physical-Chemical Properties of Binary and Multicomponent Semiconductors in CdS–ZnSe and CdS–ZnS Systems

详细

Solid substitution solutions in CdS–ZnSe and CdS–ZnS systems have been fabricated and certified. Bulk (crystal chemistry, structural, and optical) and surface (acid–base) properties of these solutions have been examined as compared to each other and their binary components. Regularities of changes in the investigated properties upon changes in the systems’ compositions and in a series of analogs have been established: these regularities have predominantly exhibited an extremal nature. Interrelations between the established regularities have been validated, which allows predicting, based only on bulk properties, the surface activity of advanced materials (fabricated solid solutions) toward gases of varied electronic nature—components of natural and technological media. Practical guidelines on application of these materials to produce appropriate sensors have been provided.
