Abstract

A comparative analysis of the edge absorption spectra measured in the temperature range of 290–470 K for two types of zinc selenide substrates has been carried out. It has been established that the self-absorption edge of pure ZnSe: Yb melt crystals is described by the «crystalline» approximation of the general Urbach rule, which is a consequence of dynamic disordering. In samples doped with ytterbium, at 330 K, a reversible transition from dynamic to static disordering was detected, which is described by the “glassy” approximation of the general Urbach rule.
