This page shows an oxygen vacancy migrating in the perovskite material BaTiO_3. This work was motivated by [1] A. Dawson, Phys. Status Solidi B 2020, 257, 1900422. DOI: 10.1002/pssb.201900422
Perovskite materials are interesting for their functional use due to electrical and magnetic properties. Some of these interesting electrical properties are due in part to ion diffusion within the material. Pictured above is the diffusion of an oxygen vacancy within a BaTiO_3 cubic phase crystal.1
