First-principles calculation of electron-phonon coupling in doped KTaO
Tobias Esswein, Nicola A. Spaldin
Motivated by the recent experimental discovery of strongly surface-plane-dependent superconductivity at surfaces of KTaO single crystals, we calculate the electron-phonon coupl…

Ferroelectric, quantum paraelectric or paraelectric? Calculating the evolution from BaTiO to SrTiO to KTaO using a single-particle quantum-mechanical description of the ions
Tobias Esswein, Nicola A. Spaldin
We present an inexpensive first-principles approach for describing quantum paraelectricity that combines density functional theory (DFT) treatment of the electronic subsystem with…

Interplay between Ferroelectricity and Metallicity in BaTiO
Veronica F. Michel, Tobias Esswein, Nicola A. Spaldin
We explore the interplay between ferroelectricity and metallicity, which are generally considered to be contra-indicated properties, in the prototypical ferroelectric barium titana…
