Anisotropic conductivity of PbFCl
Abstract
Single crystals of undoped PbFCl have been grown. The ionic conductivity of these crystals has been measured parallel and perpendicular to the crystallographic c-axis, and has been compared with the ionic conductivity of undoped β-PbF 2 and PbCl 2 single crystals. According to Greenwood the crystal structures involved favour the presence of anion Frenkel defects. In spite of the fact that conductivity experiments on undoped materials are not conclusive, the present results, together with structural considerations, favour the presence of Schottky defects.
