On thermally stimulated currents under dispersive transport regime

TSDC spectroscopy of relaxational and interfacial phenomena

“…The TSDC technique was successfully used to determine the trap energy distribution of polymer thermoelectrets, glasses and other systems [204][205][206][207][208][209]. Results reveal the existence of some groups of localized states, which are not detected by conventional TSDC [204,[210][211][212][213].…”

Thermally stimulated currents in amorphous solids due to complex heating regimes

“…The following considerations are based on the description of TSCs given in [9]. A continuous distribution of trapping states in the energy gap was presupposed.…”

“…Although the sample heating was assumed to be linear, the given formulas should also apply to other heating schemes. For reader's convenience, in Appendix A basic formulas derived in [9] are repeated.…”

“…In the most commonly used theory of Fritzsche and Ibaraki [1], improved by other authors [4,6], the carrier retrapping was ignored or treated in an approximate manner. In other theories the processes of carrier trapping/release were described by simplified equations, corresponding either to strongly non-equilibrium [8][9][10] or to quasi-equilibrium [11] distributions of trapped carriers. An alternative theory, assuming hopping carrier transport, was developed by Baranovskii et al [7].…”

“…In the present work, the theory [9] is extended to mentioned complex modes of sample heating. It is shown that the predicted TSC features are consistent with those established experimentally.…”
