Abstract
The electronic parameters of the lithium thiogallate LiGaS2 have been evaluated by X-ray photoelectron spectroscopy (XPS). Spectral features of all constituent element core levels and Auger lines have been considered. The Ga–S bonding effects in Ga-bearing sulfide crystals have been discussed using binding energy difference Δ2p(S–Ga) = BE(S 2p) − BE(Ga 3d) as a representative parameter to quantify the valence electron shift from gallium to sulfur atoms. The value Δ2p(S–Ga) = 141.9 eV found for LiGaS2 is very close to that evaluated for AgGaS2. This relation is an indicator of closely coincident ionicity of Ga–S bonds in LiGaS2 and AgGaS2.
