Semiconductor alloys provide a means of tuning properties so as to optimize and widen the application of semiconductor devices. A companion volume to Ternary Alloys Based on II-VI Semiconductor Compounds (CRC Press, 2013) and Quaternary Alloys Based on II-VI Semiconductor Compounds (CRC Press, 2014), this reference focuses on phase equilibriums in multicomponent systems based on II-VI semiconductor compounds. The book collects all available data and constructs phase diagrams of all the main II-VI systems. It includes data previously only published in Russian and difficult to access in the West. It is an invaluable data source for scientists involved in developing and manufacturing II-VI semiconductors.
