Absorption and photoconductivity spectra of Ag 2GeS 3 crystal: Experiment and theory
(Elsevier B.V., 2012-07)
Spectral features of polycrystalline Ag 2GeS 3 samples synthesized from high-purity elements (at least 99.99 wt.% purity) in quartz ampoules evacuated to 0.1 Pa were explored. The band energy gap of Ag 2GeS 3 crystals ...
Electronic spectral parameters and IR nonlinear optical features of novel Ag 0.5Pb 1.75GeS 4 crystal
(Elsevier B.V., 2012-09)
In this paper, we report on novel Ag0.5Pb1.75GeS4 single crystals grown by the Bridgman–Stockbarger method. For these crystals we have performed X-ray photoelectron spectroscopy (XPS) studies of the valence-band and ...
