TSC and dielectric response

The thermally stimulated current (TSC) technique is quite useful for studying the dielectric properties of materials. In the present paper the theory of TSC for systems having a response function exp (- t τ)β with 0 < β ≤ 1 is described. This non-exponential response function proposed by Williams et al. does not necessarily involve a distribution in relaxation times or activation energies. Hence the interpretation of TSC data without resorting to different distribution functions is possible. © 1979.
