The flexoelectricity of barium and strontium titanates from first principles
2010
Journal of Physics: Condensed Matter
Preserved Fulltext
We present ab initio calculations of the longitudinal flexoelectricity for BaTiO 3 and SrTiO 3 using a direct approach. The calculated value for SrTiO 3 agrees with recently reported measurements. For BaTiO 3 , however, the theoretical values are smaller than the measured ones; possible reasons for the discrepancy are discussed.
