Abstract

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.
