Australian researchers describe the first observation of a native ferroelectric metal: a native metal with bistable and electrically switchable spontaneous polarization states—the hallmark of ferroelectricity. The study found coexistence of native metallicity and ferroelectricity in bulk crystalline tungsten ditelluride (WTe2) at room temperature. A van-der-Waals material that is both metallic and ferroelectric in its bulk crystalline form at room temperature has potential for nano-electronics applications. The study represents the first example of a native metal with bistable and electrically switchable spontaneous polarization states—the hallmark of ferroelectricity. "We found coexistence of native metallicity and ferroelectricity in bulk crystalline tungsten ditelluride (WTe2)...
