Almost thirty years after the remarkable monograph of K. Zanio and the numerous conferences and articles dedicated since that time to CdTe and CdZnTe, after all the significant progresses in that field and the increasing interest in these materials for several extremely attractive industrial applications, such as nuclear detectors and solar cells, the edition of a new enriched and updated monograph dedicated to these two very topical II-VI semiconductor compounds, covering all their most prominent, modern and fundamental aspects, seemed very relevant and useful.

• Detailed coverage of the main topics associated with the very topical II-VI semiconductor compound CdTe and its alloy CZT
• Review of the CdTe recent developments
• Fundamental background of many topics clearly introduced and exposed
