Thermomechanical Stabilization of Electron Small Polarons in SrTiO₃ Assessed by the Quasiharmonic Approximation
We predict a predominance diagram for electron defects in the temperature-hydrostatic stress space for SrTiO₃ by combining density functional theory and the quasiharmonic approximation. We discovered two regimes where small polarons dominate: under tensile stress at lower temperature due to a larger...
