摘要

采用射频(RF)等离子方法

对GaAs样品进行了150 W高功率等离子氮钝化及快速退火处理。经过该方法钝化后的样品

光致发光(PL)强度上升了91%。XPS分析得出

GaAs样品表面的氮化效果随着氮等离子体功率的增加而逐渐趋于明显。氮化后的样品表面未发现氧化物残余。样品在空气中加热放置30 d

PL强度下降不明显

说明表面钝化层具有良好的稳定性。

Abstract

GaAs substrate was treated by N

with 150 W RF plasma and followed by rapid thermal annealing. The PL intensity increased by 91%. XPS analysis indicates that GaAs surface has been nitrided after high power RF N

plasma processing

and the nitridation effect is enhanced under higher RF power. No oxide is found on nitrided GaAs surface. The prepared samples were kept on heat plate in open air for PL stability evaluation

little drop was found during a 30 days test.
