Mercury cadmium telluride (MCT) as an important infrared detector materials widely used in preparation of 8-14 m (LWIR sensor) and 3-5 m (AM infrared MWIR) atmospheric window of infrared detector.MCT infrared detectors because of the important performance parameters - detection rate,response rate and with the noise of non-equilibrium MCT carrier lifetime is directly related to,Therefore in order to be able to produce high quality MCT IR detectors,MCT to be non-equilibrium carrier lifetime and the structural study to determine their understanding of the complex life,so as to improve life expectancy and improve the performance of the device purpose
