| 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. |
