Thermally induced charge relaxation in $\alpha$-LiIO$_{3}$ superionic conductor

Electrical properties of single crystals of $\alpha$-LiIO$_{3}$ superionic conductor (hexagonal symmetry, sp. gr. $P$6$_3$22, $z$ cut) have been studied by the methods of impedance spectroscopy and thermally induced depolarization. The mechanism of thermally induced charge relaxation in $\alpha$-LiIO$_{3}$ crystal is related to “hopping” migration of mobile Li$^+$ ions via crystallographic sites in the channels of the [IO$_{3}$]$^{-}$ crystalline framework oriented along the $c$ crystallographic axis.
