Calculation of thermally stimulated depolarization current from isothermaldielectric response data

Thermally stimulated depolarization is modeled from dielectric response fun ctions deduced from isothermal measurements. The key assumption made is tha t the same state of polarization can be achieved both via the real non-isot hermal thermally stimulated depolarization (TSD) process and via an equival ent isothermal process. The change of polarization with temperature and tim e is traced through a continuous adjustment of the starting and stopping ti mes and polarizing field of the fictitious isothermal process. The theory i s applicable to general cases of non-Debye relaxation with variable activat ion energy. A comparison of the modeled and measured TSD thermograms is pre sented for films.
