Ferroelectric Semimetals with $\alpha$-Bi/SnSe van der Waals heterostructures and its Topological Currents

D. J. P. de Sousa, Seungjun Lee, Qiangsheng Lu +5

We show that proximity effects can be utilized to engineer van der Waals heterostructures (vd- WHs) displaying spin-ferroelectricity locking, where ferroelectricity and spin states…
