Sliding-ferroelectric order imprinted onto excitonic and valley responses in van der Waals heterostructures

Ferroelectricity driven by interlayer sliding provides a distinct route to nonvolatile control in van der Waals (vdW) heterostructures, yet resolving stacking-dependent ferroelectric states and their local interfacial consequences remains challenging. Here, we report that bilayer...
