Abstract :
ZnO nanowires were treated with ammonia(NH3) plasma. Electrical and field emission properties of the same individual ZnO nanowire were investigated before and after NH3 plasma treatment. Lowered work function, increased resistance and lowered turn-on field was observed. Ammonia molecule substitutional defect on Zn site was attributed to the observed phenomena.
