This paper reports the temperature dependence of d.c. and a.c. conductivity in the glassy alloys of Se70Te30 and Se70Te28M2 (M = Cd, Sb, Zn). The role of the Cd, Sb, Zn elements as foreign atoms has been examined on the d.c./a.c. conduction and photoconduction in binary Se70Te30 glass. These multi-component chalcogenide glasses have been prepared by conventional, cost-effective and well-known melt-quench technique. Thermally activated a.c. conduction shows the presence of the compensation effect that is confirmed by the Meyer–Neldel relation between the associated activation energy and the pre-factor of a.c. conductivity. The metal-induced effects of Cd, Sb, Zn on the photosensitivity of parent glass are also discussed.
