Sažetak
Electrical conductivity of Cu7(Ge1-xSix)S5I mixed crystals was measured in the frequency range 1.0106–1.2109 Hz and in the temperature interval 100–300 K. The frequency and temperature behaviour of the electrical conductivity were analyzed. The optical absorption edge of Cu7(Ge1-xSix)S5I mixed crystals in the temperature range 77–300 K was studied. The compositional dependences of the electrical conductivity, activation energy, optical pseudogap and Urbach energy were obtained. The influence of Ge-Si cation substitution on the optical absorption processes in the Cu7(Ge1-xSix)S5I mixed crystals is investigated.
