Temperature Dependence of the Band-Gap Width of Mn1.5AgIn8.0S14 Single Crystals

  • Published:
Journal of Applied Spectroscopy Aims and scope

Mn1.5AgIn8.0S14 single crystals were grown by Bridgman directed melt crystallization. Their composition and crystal structure were determined. Single crystals crystallized in the cubic spinel structure with lattice constant a = 10.765 ± 0.005 Å. The band-gap width of Mn1.5AgIn8.0S14 single crystals was estimated from transmission spectra near the intrinsic absorption edge in the temperature range 10–320 K and decreased with increasing temperature. A function approximating this dependence was obtained.
