Electrical conductivity of KH(2)AsO(4) and KD(2)AsO(4)
Article (191.3Kb)Abstract
Measurements of the electrical conductivity of KH(2)AsO(4) and its deuterated isomorph have been performed from room temperatures to the temperature of their respective ferroelectric transitions. Activation energies of 0.66 and 0.64 eV have been found to characterize the temperature dependence of the conductivity for KH(2)AsO(4) and KD(2)AsO(4), respectively. Further evidence that these materials display anomalously long polarization relaxation times near the temperature of the ferroelectric transition is presented and discussed. the nature of this behavior remains unexplained.
