摘要: Various optical and electrical properties of Na‐ Li‐diffused samples CdS have been studied. Samples were prepared under maximum sulfur pressure, both with without simultaneous donor doping. In the absence donors, p‐type material cannot be obtained, specific alkalis unraveled. intentionally added Na Li are ``good'' acceptors, a binding energy consistent previous determinations (∼0.17 eV). Under certain conditions, has shown to act primarily as donor. The various compensation mechanisms discussed.
