Study of Surface Lapping and Polishing Methods of Cadmium Zinc Telluride
Abstract:Cadmium Zinc Telluride (CZT) is a II-VI compound semiconductor material with excellent performance. Its energy gap can be tuned continuously with different zinc content. So it is an excellent substrate material for the HgCdTe material to be used to manufacture infrared detectors. Several lapping and polishing methods of cadmium zinc telluride including hand lapping, mechanical polishing, chemical polishing, mechanochemical polishing are presented. With the aid of various characterization techniques and reformed methods, significant progresses have been made in the surface processing of CZT.
