Investigation of compensation effect for isothermal crystallization in glassy Se80−xTe20Mx (M = Cd, Ge, Sb) alloys

The compensation effect (also known as the Meyer–Neldel (MN) 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 investigated the compensation effect for isothermal crystallization in glassy Se80−xTe20Mx (M = Cd, Ge, Sb) alloys. The extent of crystallization was estimated from the dc conductivity measurements for the present chalcogenide glasses. We have observed the MN rule relating the pre-exponential factor K0 and the activation energy of crystallization Ec for all three glassy systems.
