摘要
在n型ZnO体单晶片上,首次采用N等离子体辅助金属有机化学气相沉积方法外延生长了p型ZnO薄膜,制成了同质ZnO的发光二极管(LED)原型器件;在室温下,观察到同质ZnO的LED施加电压后由电注入激发出紫外至绿光波段的光谱.
p-type zinc oxide (ZnO) thin films are grown by plasma-assisted metalorganic chemical vapor deposition (MOCVD). A ZnO homostructural light-emitting diode is fabricated by growing p-type ZnO epi-layer on n-type bulk ZnO wafer. The room temperature electroluminescence spectrum from violet to green regions is observed while the ZnO-LED is supplied with a DC voltage.
