The typical infrared detectors as a function of wavelength are PbS of the 1-3㎛, InSb of 3-5㎛ and Si and Ge for impurites types materials. But its properites is not better than HgCdTe at the time constant and response temperature and response wavelength range. The HgCdTe materials for a IR-detector at wavelength range 3-5㎛ for composition x= 0.3 and 8-14㎛ for composition x= 0.2 at 77K and 300K respectvily. The Hall data of HgCdTe grown by THM was p type and the energy gap(E_g) were measured by optical absorption coefficient at composition range of 0.197≤x≤0.300.
