Abstract
It was pointed out by Schön in 1958 that the analysis of thermoluminescence and thermally stimulated conductivity can be simplified by using a quadratic rate of heating. The fact that such a rate of heating is feasible in practice has given a stimulus to review the theories of TL and TSC in this light. In this paper it has been shown that in the second-order kinetics of the Garlick and Gibson model, theoretically the TSC curve should not exhibit any peak with the quadratic rate of heating under charge neutrality condition, rather it should tend asymptotically towards a constant value. Thus the usual methods of analysis utilizing the temperature of maximum TSC for the estimation of trap depth would not be applicable. This non-occurrence of the peak is found to be due to the temperature dependence of the mean lifetime of the free electron in the conduction band.
