Correlation between Meyer–Neldel rule and phase separation in Se98−xZn2Inx chalcogenide glasses
چکیده انگلیسی

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 K0 of rate constant K(T) of crystallization and activation energy of crystallization Ec 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.
