Abstract

The effect of arsenic doping on optical characteristics of ZnO nanowires was investigated by photoluminescence spectroscopy carried out at 13-290 K. In as-grown nanowires, emission due to acceptor-bound excitons predominated at low temperatures; as temperatures increased, emission due to recombination of free excitons prevailed. Arsenic-doped nanowires exhibited emission due to acceptor-bound excitons with no free exciton emission in the whole temperature range, indicating the formation of the acceptor level within the ZnO nanowire by arsenic doping.
