II-VI Compounds covers the general idea of the way in which II-VI compounds behave. The book describes the fundamental nature of II-VI compounds; the preparation and single crystal growth; and the fundamental optical properties of II-VI compounds. The text also discusses the luminescence; the photo conductivity and associated behavior; the transport properties; and the applications of II-VI compounds. Students taking materials science or engineering courses will find the book useful.
