Abstract
D. C. electrical conductivity of Ge-S and Ge-V-S glassy systems were s tudied. It was found that so called Mott minimum metallic conductivity is function of activation energy of d.c. electrical conductivity for all studied glasses. The explanation based on idea of exponential tail of valence band edge and the p-type of electrical conductivity in ext ended states close to the mobility edge of valence band was suggested.
