Pre-exponential factor of Arrhenius equation for the isothermal crystallization of some Se–Ge, Se–In and Se–Te chalcogenide glasses

Abstract

Compensation law or Meyer–Neldel rule is observed in many activated phenomena, including solid state diffusion in crystals and polymers, dielectric relaxation, conduction and thermally stimulated processes in polymers, and electronic conduction in amorphous semiconductors. In the present paper, we have reported the compensation effect for the isothermal crystallization of some Se–Ge, Se–In and Se–Te chalcogenide glasses. We have observed Meyer–Neldel rule between pre-exponential factor K0 and activation energy of crystallization Ec in the present case.
