摘要
报道了一种面积为９ｍｍ２的ＧａＡｓ肖特基势垒粒子探测器，其反向耐压高于４００Ｖ，反向漏电流低于１２５ｎＡ（ＶＲ＜－１５０Ｖ）。器件经受能量为３ＭｅＶ、剂量为５００ｋＧｙ的电子辐照后，反向漏电流为２７０ｎＡ（ＶＲ＝－１５０Ｖ）。说明在高能物理和核物理中很有应用前途。
The radiation hardness of GaAs Shottky barrier particle detectors has been tested. The leakage current at reverse voltage VR<-150V is lower than 125nA. After a 3MeV electron radiation of 500kGy, the leakage current is changed to 270nA at VR=-150V.It is a promising detector in both high energy and nuclear physics.
