Abstract

From the analysis of the spectra of photoluminescence and transparency in the temperature interval (2–77) K there are determined in the paper, the gap-width and its temperature coefficient as a function of the composition of the melt of (AlSb)x(HgTe)1−x. It is shown that for compositions (0.8 ≤x ≤ 1) with a lowering of the temperature, the edge of the fundamental absorption is shifted into the domain of large energies, and for compositions (0.05 ≤, x ≤0.20) with a lowering of temperature, the edge of the fundamental absorption is shifted into the long-wave domain of the spectrum. The dependence of Eg(x, T) has a nonlinear character.
