The Physics of Copper Oxide (Cu2O)

Abstract The physics of cuprous oxide (Cu 2 O) is reviewed with respect to structural, optical, and electrical properties. New experimental findings are included especially in the context of theoretical band-structure calculations. Intrinsic defects related to nonstoichiometry are made responsible for the p-type conduction. First preliminary experiments on the alloying of Cu 2 O by sulfur are reported.
