NITROGEN DOPING IN ZNSE AND ZNTE

We present a theoretical investigation and discussion of N doping in Z nSe and ZnTe, based on first-principles calculations. We find that the experimentally observed trend in doping efficiency can be attributed to the higher solubility of N in ZnTe. We also discuss the potential f ormation of complexes between the N acceptor and native defects, the c hange in lattice constant of ZnSe due to heavy N doping, and some prob lems associated with N as an acceptor dopant.
