Ferroelectric switching of a two-dimensional metalFerroelectric switching of a two-dimensional metal, Published online: 23 July 2018; doi:10.1038/s41586-018-0336-3Two- and three-layer WTe2 exhibits spontaneous out-of-plane electric polarization that can be switched electrically at room temperature and is sufficiently robust for use in applications with other two-dimensional materials.
