Nonvolatile electrical switching of nonreciprocal transport in ferroelectric polar metal WTe₂.

ABSTRACT: Nonreciprocal charge transport in junction-free devices has gained strong research interest recently, due to its capabilities to reveal new quantum physics and potential in outperforming traditional junction-based nonreciprocal devices. While nonreciprocal transport has been reported in a wide range of materials due to various exotic physics, the direction of nonreciprocity is mostly fixed. A key capability that has not been established is the active control of the direction of nonreciprocity. Here by taking advantage of the unique and intrinsic coexistence of switchable ferroelectricity and magnetochiral anisotropy in few-layer polar metal WTe₂, we demonstrate nonvolatile electrical switching of nonreciprocal transport. The direction of nonreciprocal transport is reversed upon
