Atomistic simulation of paratellurite α-TeO<sub>2</sub> crystal. III. Anisotropy of ion transport under externally applied electric fields

The features of ion transfer in α-TeO2 paratellurite crystals under conditions of an external constant electric field have been studied by the method of molecular dynamics. It is shown that the anisotropy of ion transport is more pronounced when the E field is applied along the c axis: at E = 350 kV/mm, diffusion increases by about 2 times for crystals with oxygen vacancies and 3 times for samples with additional interstitial oxygen atoms.
