摘要
The isoelectronic doping of ZnTe with oxygen leads to deep levels on which carriers recombine radiatively via intermediate band states. The electronic density and the impurity-host character of these deep levels are analyzed using first principles, for the wurtzite and zinc-blende structures, different oxygen concentration, and different exchange-correlation approach.
