The metal-to-insulator transition in polar metals

ORAL

Abstract

The fundamental design principles that drive a switchable polarity in oxide-based
electronics whilst preserving a metallic state are not well understood. This is partly because it
requires the coexistence of two seemingly incompatible properties: ferroelectric polar
distortions and metallic conductivity. We study the prototypical polar metal LiOsO3 as a
function of strain, which acts as a benchmark to further elucidate the role of electronic
correlations in the alkali osmate perovskite-based series. Building on these results, we report a
fully correlated DFT+DMFT approach to search and design new polar metals.
