摘要：

The present work reports the observation of Meyer-Neldel rule for the thermally activated crystallization of glassy Se98-xZn2Inx (0 <= x <= 10) alloys. We have observed a strong co-relation between the pre-exponential factor K-o of rate constant K(T) of crystallization and activation energy of crystallization E-c in the present case. This indicates the presence of compensation effect for the non-isothermal crystallization process in the present glassy system, which is explained in terms of phase separation of the present alloys due to flaw bonds of these amorphous solids.
