摘　　要：对（HgCd）Te探测器峰值响应波长的Franz－Keldysh偏移进行了实验研究。实验结果表明，在强电场中，（HyCd）Te具有很强的Franz－Keldysh效应，因而可能导致光吸收峰值波长向长波长方向的明显偏移。The Franz-Keldysh shift of the wavelength of peak response of (HgCd) Te detectors has been investigated experimentally. Our experimental measurements show that the Franz-Keldysh effect does have significant strength in (HgCd)Te and may lead to a considerable shift of the optical absorption edge toward the longer wavelength in a strong electric field.
