In the present communication, d.c. conductivity of a-Se 80 Te 20 and a-Se 80 Te 10 M 10 (M = Cd, In, Sb) alloys has been studied in the temperature range 225–311 K in order to identify the conduction mechanism and to analyze the effect of different metallic additives on d.c. conduction in a-Se 80 Te 20 alloy below the room temperature. An analysis...
Temperature and frequency dependence of a.c. conductivity have been studied in glassy Se 70 Te 30−x Sb x (4 ≤ x ≤ 10) alloys. The observation of Further Meyer–Neldel rule in case of a.c. conductivity is reported. The observation of the correlation between Meyer–Neldel pre-factor σ 00 and Meyer–Neldel energy is explained by multiple excitations stimulated by optical...
In the present paper, we report the observation of the Meyer–Neldel rule (MNR) in thermally activated high field conduction in bulk samples of glassy Se 100−x Sb x alloys. We have investigated Meyer–Neldel rule by two different approaches.In first approach, the temperature dependence of d.c. conductivity is studied at different electric fields without changing the composition of the...
