On the problem of activation energy of thermal decay of color centers and similar non-stationary processes

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

Thermally stimulated process is discussed as a superposition of components with equal activation energy and a distribution of frequency factors. Changes of concentrations of individual components of this process proceed according to first order rate law. A relationship between Laplace transformation of the distribution of frequency factors and the law governing the resulting changes of the concentration is studied. An application on the thermal decay of F-centers indicates that actual activation energy tends to be greater than the energy resulting e.g. from Urbach analysis. Experimental procedures are proposed allowing the actual activation energy and the distribution of frequency factors to be determined.
