Electron Mobilities in SrTiO${}_3$ and KTaO${}_3$: Role of Phonon Anharmonicity, Mass Renormalization and Disorder

Luigi Ranalli, Carla Verdi, Marios Zacharias +3

Accurately predicting carrier mobility in strongly anharmonic solids necessitates a precise characterization of lattice dyndamics as a function of temperature. We achieve consisten…
