Abstract

A high photo-sensitive area has been created in solid solution of Hg_1-xCd_xTe (x approximately equals 0.2) (MCT) without melting its surface. That idea of formation of heterojunction, which was indicated by computer modelling of mass transportation processes under laser treatment of MCT, is realized experimentally. MCT samples were irradiated with a Nd:YAG laser beam having an energy density 0.7 J/cm². The presence of a heterojunction not far below the upper surface has been verified by X-ray microanalysis.
