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.

    Two-terminal devices of Cu2S/ZnO core/shell nanowires were fabricated and measured. Forward bias sweeping produced a rectified I-V characteristic of a diode, with turn-on voltages varying from 150 to 300 mV. The turn-on voltages depended on the rate at which the bias was varied. When the bias...
