Chalcogenide glasses that contain sufficient concentrations of metal atoms can be doped p-type. This doping results in part because the local structural order is tetrahedral at both the metal and the chalcogen sites in these glasses. At concentrations exceeding 1019 см-3, oxygen promotes doping by increasing the densities of dangling-bond defects at 3-fold-coordinated chalcogens, which are the doping sites in these glasses. For oxygen concentrations below 1019 см-3, the conductivity is independent of oxygen and, therefore, is controlled by other mechanisms. The compositions Cu6As4S9 and Cu6As4Se9 are studied because at these compositions the S (or Se) and Cu atoms are all tetrahedrally coordinated and there exist only Cu--S and As--S (or Cu--Se and As--Se) bonds.
