Abstract

Temperature and frequency dependence of a.c. conductivity have been studied in glassy Se70Te30−xSbx (2 ≤ x ≤ 10). An agreement between experimental and theoretical results suggests that the a.c. conductivity behaviour of Se-Te-Sb system can be successfully explained by correlated barrier hopping (CBH) model. The observation of Meyer-Neldel rule in case of a.c. conductivity at high temperatures is also reported for glassy Se70Te30−xSbx (2 ≤ x ≤ 10) alloys.
