Solar-blind GaN-based UV Detectors with Two Structures
【摘要】 分别在金属有机化学汽相沉积(MOCVD)生长的i-A l0.33Ga0.67N/A lN/n-GaN和p-A l0.45Ga0.55N/i-A l0.45Ga0.55N/n+-A l0.65Ga0.35N的异质结构上,成功研制了太阳盲区的肖特基型和PIN型紫外探测器。研究结果表明,Au与i-A l0.33Ga0.67N形成了较好的肖特基结,响应波长从250~290nm,峰值(286nm)响应率约为0.08A/W;PIN型紫外探测器的响应波长从230~275nm,峰值(246nm)响应率约为0.02A/W。
【Abstract】 Solar-blind AlGaN Schottky and PIN UV photodiode have been successfully demonstrated on MOCVD-grown i-Al0.33Ga0.67N/AlN/n-GaN and p-Al0.45Ga0.55N/i-Al0.45Ga0.55N/n+-Al0.65Ga0.35N hetero-structure.The result shows that good Schottky diode is formed on Au/i-Al0.33Ga0.67N,response wavelength of detector changes from 250nm to 290nm with the peak responsivity of 0.08A/W.Response wavelength of PIN UV detector changes from 230nm to 275nm with the peak responsivity of 0.02A/W.
