GROWTH, STRUCTURE, AND TEMPERATURE DEPENDENCE OF THE BAND GAP OF Mn0.3Ag0.7In4.1S6.8 SINGLE CRYSTALS
Abstract
Mn0.3Ag0.7In4.1S6.8 single crystals were grown by directed melt crystallization, their composition and crystal structure were determined. It was established that the single crystals Mn0.3Ag0.7In4.1S6.8 crystallize in a cubic spinel structure. The band gap of the single crystals was estimated from the transmission spectra in the region of the fundamental absorption edge in the temperature range of 20–320 K, and its temperature dependence was constructed. It was shown that the temperature dependence of the band gap has the form characteristic for semiconductor materials.
