Abstract

Based on empirical rules for the intrinsic absorption coefficient and refractive index of Hg_1-xCd_xTe in Hougen's model, a novel calculation method determining the composition profile of epitaxy layer from room- temperature infrared transmittance spectroscopy is presented. The composition depth profile of Hg_1-xCd_xTe film samples grown by liquid-phase epitaxy and after annealing is determined using this method. The expression of the composition interdiffusion coefficient for Hg_1-xCd_xTe was deduced.
