| Abstract: | Hg_(1-x-y)Cd_xZn_yTe (MCZT) crystals were grown by travelling heater method (THM) as a promising material for infrared detectors. The investigations of optical characteristics, structural characteristics, electrical properties and composition homogeneity were carried out on the MCZT wafers after annealed in Hg vapor for an appropriate time. The wafers were then made into photoconductive devices and the device characteristics were also studied. The results showed that it was successful to grow MCZT crystals by THM. The material characteristics and device properties of MCZT were desirable for practical application. |
