Abstract
The frequency (ν = 10−1–107 Hz) dependences σ(ν) of the conductivity of single crystals of the Pb0.67Cd0.33F2 superionic conductor with the fluorite-type structure (CaF2) in the temperature range of 132–395 K have been studied. The dependences σ(ν) have been discussed in the framework of the hopping relaxation of ionic carriers, which are mobile anions F−. From experimental curves σ(ν), the direct-current (dc) conductivity σdc and the average charge carrier hopping frequency νh have been determined. This has made it possible to calculate the charge carrier mobility μmob and charge carrier concentration n mob in these crystals. At room temperature (293 K), the electrical parameters are σdc = 1.6 × 10−4 S/cm, νh = 2.7 × 107 Hz, μmob = 2.0 × 10−7 cm2/(s V), and n mob = 5.1 × 1021 cm−3.
