Abstract
An accuracy of the initial rise method is considered, as applied to the determination of the activation energy from thermoluminescence and thermally stimulated conductivity spectra. The method is analyzed in the classical case described by the simple trap model as well as in the presence of spatial correlation between traps. For this purpose a novel, generalized version of the Monte Carlo algorithm was developed. It allows to simulate TSR processes with an arbitrary heating function applied that gives the possibility of simulating the use of the initial rise method and the fractional glow technique. An influence of initial filling of traps on the initial rise method is analyzed. It is confirmed that for sufficiently low initial concentration of charge carriers in traps the method gives correct values of the activation energies even in the case of strong retrapping. This conclusion is valid irrespective of the spatial correlation between traps and recombination centers.
