Thermoluminescence and trap assemblies - Results of Monte Carlo calculations

Thermoluminesence (TL) glow curves depend on the spatial distribution of traps and recombination centres. Only two limiting cases are described by analytical theories: the model of trap-recombination centre pairs (known as the localized transitions model) and the simple model, that assumes homogeneous (or random) distribution of traps and recombination centres. Applying Monte Carlo methods we present some properties of TL in the intermediate cases of spatial correlation. The calculations were performed for monenergetic trap level and two-level system. The range of applicability of standard theoretical models is estimated. (C) 1998 Elsevier Science Ltd. All rights reserved.
