DEPENDENCE OF PERFORMANCE ON THE FIXED SURFACE CHARGES IN Hg 1- x Cd x Te PHOTOCONDUCTOR

研究了表面固定电荷密度对ＨｇＣｄＴｅ光导探测器性能的影响，计算结果表明，表面固定电荷对器件的性能有着重要的影响，选择合适的钝化工艺，控制表面固定电荷密度。

The effect of fixed surface charge density on the performance of HgCdTe photoconductive detectors was presented in this study. The calculations show that the fixed surface charges can influence the characteristics of the detector greatly. Optimum of the fixed surface charges governed by the passivation processes can improve the device performance.
