Significance of the dispersion force for ferroelectric switching in ZnO and related materials
Lingyao Zhang, Musen Li, Nisha Metha +3
Wurtzite-ZnO is a wide-bandgap polar material with a ferroelectric-switching barrier that is too high to utilize, but the barrier can be reduced and switching observed in substitut…
First-principles theory of nonlinear long-range electron-phonon interaction
Matthew Houtput, Luigi Ranalli, Carla Verdi +4
Describing electron-phonon interactions in a solid requires knowledge of the electron-phonon matrix elements in the Hamiltonian. State-of-the-art first-principles calculations for…
First-principles theory of nonlinear long-range electron-phonon interaction
Matthew Houtput, Luigi Ranalli, Carla Verdi +4
Electron-phonon interactions in solids are crucial for understanding many interesting phenomena, such as conventional superconductivity, temperature-dependent band-gap renormalizat…
Electron Mobilities in SrTiO and KTaO: 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…
