Multilayer engineering of CaVO thin films with SrTiO and LaAlO from DFT+DMFT

Sophie Beck, Claude Ederer

In this paper we use density functional theory combined with dynamical mean-field theory (DFT+DMFT) to study interface effects between thin films of the correlated metal CaVO a…

Electronic Localization in CaVO3 Films via Bandwidth Control

Daniel E. McNally, Xingye Lu, Jonathan Pelliciari +11

Understanding and controlling the electronic structure of thin layers of quantum materials is a crucial first step towards designing heterostructures where new phases and phenomena…

On the effect of charge self-consistency in DFT+DMFT calculations for complex transition metal oxides

Alexander Hampel, Sophie Beck, Claude Ederer

We investigate the effect of charge self-consistency (CSC) in density functional theory plus dynamical mean-field theory (DFT+DMFT) calculations compared to simpler "one-shot" calc…

Charge transfer in LaVO/LaTiO multilayers: strain-controlled dimensionality of interface metallicity between two Mott insulators

Sophie Beck, Claude Ederer

We use density functional theory plus dynamical mean-field theory to demonstrate the emergence of a metallic layer at the interface between the two Mott insulators LaTiO and La…

Hund excitations and the efficiency of Mott solar cells

Francesco Petocchi, Sophie Beck, Claude Ederer +1

We study the dynamics of photo-induced charge carriers in realistic models of LaVO3 and YTiO3 polar heterostructures. It is shown that two types of impact ionization processes cont…
