Charge-order-induced ferroelectricity in LaVO${}_3$/SrVO${}_3$ superlattices

Se Young Park, Anil Kumar, Karin M. Rabe

The structure and properties of the 1:1 superlattice of LaVO${}_3$ and SrVO${}_3$ are investigated with a first-principles density-functional-theory-plus-$U$ (DFT+$U$) method. The…
