Abstract
The effect of the catalysis of transition metal such as tungsten (W) and iron (Fe) on nitrogen doping into ZnSe was investigated for the first time. In a hot W filament, the intensity of the donor-acceptor pair (DAP) emission in the N-doped ZnSe films using W filament at a temperature of 2000°C was stronger than that without heating of the W filament. In a hot Fe tube, neutral acceptor bound excitonic emission (I 1) and DAP emission were observed in the N-doped ZnSe without heating of the Fe tube, while only DAP emission was observed with heated Fe tube at 300°C. From these results, it was found that nitrogen was effectively incorporated into ZnSe by the effect of heated transition metal.
