The electrical transport of intrinsic two-dimensional ferroelectric metal PtBi2
Dan Li, Liu Yang, Lei Li
Breaking the conventional stereotype that ferroelectrics are necessarily insulating, two-dimensional (2D) ferroelectric metals combine seemingly incompatible switchable electric po…

Two-dimensional Topological Ferroelectric Metal with Giant Shift Current
Liu Yang, Lei Li, Zhi-Ming Yu +2
The pursuit for "ferroelectric metal" which combines seemingly incompatible spontaneous electric polarization and metallicity, has been assiduously ongoing but remains elusive. Unl…
