Dielectric to pyroelectric phase transition induced by defect migration
New Journal of Physics, 2015 Subjecting strontium titanate single crystals to an electric field in the order of 10 ^6 V m ^−1 is accompanied by a distortion of the cubic crystal structure, so that inversion symmetry vanishes and a polar phase is established.
