Abstract
THERMAL recombination of positive holes and trapped electrons in irradiated solids may be regulated by two rather distinct mechanisms. The first possibility is that the electron is activated out of its trap into the conduction band, and thereby becomes “free” with an extended range before undergoing recombination or retrapping. A model of this type with a suitable distribution of trap depths was first suggested for ionic solids1, and it has since been applied to explain the radiation-induced conductivity of hydrocarbon polymers2. A second mechanism of recombination involves the diffusive motion of the trapped electron3, and this communication shows that this model predicts the absolute rate of recombination in simple hydrocarbon glasses.
