THEORETICAL-MODEL FOR THERMALLY STIMULATED LUMINESCENCE, CONDUCTIVITYAND EXOELECTRONIC EMISSION

A theoretical model which takes into account thermally stimulated lumi nescence (TSL), conductivity (TSC) and exoelectronic emission (TSEE) i s proposed in this article. The model is established for the case of a single type of electron trap, a single type of recombination centre a nd in the presence of thermally disconnected traps. It generalizes the model of Lewandowski and McKeever by taking the TSEE phenomenon into consideration. TSEE is described as resulting from the thermionic effe ct and so the model applies only to a thin solid film about 10 nm thic k. As an application example, the influence of various parameters invo lved in the model on peak shape and position is investigated.
