Insights from Experiment and Theory on Peculiarities of the Electronic Structure and Optical Properties of the Tl₂HgGeSe₄ Crystal.

ABSTRACT: Tl₂HgGeSe₄ crystal was successfully, for the first time, synthesized by the Bridgman-Stockbarger technology, and its electronic structure and peculiarities of optical constants were investigated using both experimental and theoretical techniques. The present X-ray photoelectron spectroscopy measurements show that the Tl₂HgGeSe₄ crystal reveals small moisture sensitivity at ambient conditions and that the essential covalent constituent of the chemical bonding characterizes it. The latter suggestion was supported theoretically by ab initio calculations. The present experiments feature that the Tl₂HgGeSe₄ crystal is a high-resistance semiconductor with a specific electrical conductivity of σ ∼ 10^-8 Ω^-1 cm<
