Semi-localized transitions model for thermoluminescence

A new model for thermoluminescence (TL) kinetics is presented, which is a natural generalization of the standard localized transition model. The model of semi-localized transitions (SLTs) allows trapped charge carriers to be excited to the conduction band. Analytic equations for SLTs are constructed using an enumeration technique which transforms concentrations of carriers to concentrations of states of localized trap-recombination centre pairs. Solving numerically the set of equations, we demonstrate some basic features of the SLT model. It is shown that SLT is able to produce so-called TL displacement peaks that were previously found in one-dimensional TL simulations
