Abstract: In many amorphous and liquid semiconductors and other class of materials, Meyer-Neldel rule is observed in the <i style="">dc</i> conductivity, where the pre-exponential factor (σ<sub>0</sub>) is found to increase exponentially with the activation energy (Δ<i style="">E</i>). In the present paper, the observation of Meyer- Neldel rule in case of <i style="">ac</i> conductivity near the room temperature in bulk samples of Se<sub>80</sub>Te<sub>20</sub> and Se<sub>80</sub>Te<sub>10</sub>M<sub>10<b style=""> </b></sub>(M = Cd, In, Sb) chalcogenide glasses has been reported.
