Interconnection of the parameters obtained from thermally stimulated depolarization currents in β- PbF2 doped with rare Earth ions
چکیده انگلیسی
Earlier measurements of thermally stimulated depolarization currents in cubic PbF2 containing small rare earth ions have led to the determination of the pre-exponential factor τ0 and the activation energy E involved in the Arrhenius relation τ = τ0exp(E/kT). Here, we show that these parameters are interconnected in a way governed by bulk properties. This corroborates with a very recent finding (Solid State Ionics, 179 (2008) 438) which showed that, for various defect processes, the ratio of the activation volume over the corresponding energy is also equal to a bulk quantity.
