U50.00003. The metal-to-insulator transition in polar metals

Presented by: Evan Sheridan


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 … The American Physical Society (APS) is a non-profit membership organization working to advance the knowledge of physics.
