The progress made in physics and technology of semiconductors depends main.ly on three families of materials: the group-IV elemental,Ⅲ-Ⅴ, and Ⅱ-Ⅵ compound semiconductors.Almost all ⅡⅥ compound semiconductors crystallize either in the zincblende or wurtzite structure.The first research papers on Ⅱ-Ⅶ compound semiconductors date back to the middle of the nineteenth century.In the ensuring hundred years extensive literature has been accumulated as much research and development works are being carried out on these compound semiconductors.At present, the Ⅱ-Ⅵ compound semiconductors are widely used as photodetectors, x-ray sensors and scintillators, phosphors in lighting, displays, etc.New applications are continuously being proposed.Thus, it seems to timely bring together the most up-to-date information on the material and semiconducting properties of Ⅱ-Ⅵ compound semiconductors.
