Abstract

Cd_1-yZn_yTe (CZT) wafers with (111) orientations, which serve as the common substrates for Hg_1-xCd_xTe (MCT) epitaxial deposition, were treated with different processes of mechanical polishing and chemical etching and then tested by x-ray diffraction unit with the same experimental conditions. The conclusion is that the sample surface treatment dramatically influences the values of DCRC FWHM. The most desirable process and its experimental conditions for accurate measurement of DCRC FWHM have also been reported in this paper.
