Temperature dependence of the density of optically-induced localized paramagnetic states in glassy As₂Se₃

Abstract

Optically-induced localized paramagnetic gap states in glassy As₂Se₃ have been studied as a function of temperature from 4–2 K to ∼ 150 K using E.S.R. and optical absorption techniques. The number of paramagnetic states stable at ∼ 150 K is an order of magnitude less than the number stable at low temperatures. Densities of thermal release energies for the metastable states are estimated from the data.
