摘要
在讨论（HgCd）Te探测器耗尽层宽d和光吸收系a的基础上，导出了探测器截止波长的有效Franz－Keldvsh偏低△λce与a、d的关系式，说明了实验测定的△λce偏低的原因．
The width of the depletion region d and the photon absorption coefficient a of the pn+ junction (HgCd)Te detectors are calculated. The equation about the relation among a, d and the effetive Franz - Keldysh shift ceis derived. And an interpretation of tremendous difference between cm and ceis presented.
