The heterointerface between complex oxides and van der Waals materials presents a versatile platform for exploring new functionalities. Here, the authors report an unconventional nonlinear optical filtering effect resulting from the interfacial polar alignment between monolayer MoS2 and a ferroelectric oxide thin film.
