Abstract

The Meyer–Neldel rule or MN rule (also known as compensation effect) is an empirical law known since 1937. This rule is observed in wide range of phenomena in physics, chemistry, biology and electronics. 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 obey the MN rule. In the present article, we report the MN rule in the non-isothermal crystallization in glassy Se80Te20 and Se75Te20M5 (M = Ag, Cd, In, Sb) alloys. We have observed MN rule between pre-exponential factor K o and activation energy of crystallization E c in the present case for thermally activated non-isothermal crystallization.
