A method of evaluating curves of thermally stimulated current determined experimentally is described. This is essentially one of curve fitting, and serves to determine the energy depth of traps from the excellent fit eventually obtained between the theoretical and experimental curves.
In addition to the equation for TSC with constant heating rate βc, an equation with heating rate β(T) of exponential form is derived. A numerically calculating technique is developed with application to some experimental results in anthracene single crystals excited by Q-switched ruby laser.
Theoretically numerical calculation is performed for the previously reported second group within the numerous experimentally observed peaks of TSC. The energy depth Et for this trap is evaluated to be about 0.57 eV and that the trap in anthracene single crystals is a monoenergetic state of slow retrapping nature is confirmed. The results of calculation on the effect of measured temperature error on the Et value is also reported.
