Abstract
In the present paper, we report temperature dependence of conductivity in a- Se100-xBix thin films at different electric fields. It is observed that conductivity is thermally activated with single activation energy at all the electric fields applied. However, the pre-exponential factor and activation energy are found to be dependent on electric field applied. A correlation is observed between pre-exponential factor and activation energy which is similar to Meyer-Neldel rule. The paper also reports the further MN rule in the present glassy system..
