Synthesis of Semiconducting Compounds
Mercury forms a series of important semiconducting materials. These semiconductors, typically composed of mercury, cadmium, tellurium, manganese, zinc, selenium or other metals, are used as infrared detectors, radiation detectors and fiber optic communication devices. An extensive discussion is given on the synthesis and crystal growth of these compounds. Direct and indirect synthesis, sublimation, resublimation, single-crystal growth methods, epitaxial growth methods and transport reactions are explained. The thermodynamics, vapor pressure and structure of many of the simple semiconducting compounds are given. The material requirements on homogeneity are of the utmost importance in many of these carefully grown crystals. This chapter draws heavily on Russian and Soviet-era literature.
