Abstract
ac electrical measurements are reported for the paraelectric phases of the ferroelectric CuInP2S6 and antiferroelectric CuCrP2S6. A complex permittivity analysis confirms previous dielectric results for CuInP2S 6. Arrhenius behaviors with nearly identical activation energies were observed for the de conductivities and modulus relaxation frequencies. A hopping mechanism for Cu(I) transport in these materials is thus su ggested.
