Abstract: In many amorphous and liquid semiconductors and other class of materials, Meyer-Neldel rule is observed in the dc conductivity, where the pre-exponential factor (σ0) is found to increase exponentially with the activation energy (ΔE). In the present paper, the observation of Meyer- Neldel rule in case of ac conductivity near the room temperature in bulk samples of Se80Te20 and Se80Te10M10 (M = Cd, In, Sb) chalcogenide glasses has been reported.
