We demonstrate the integration of a thin BaTiO\(_3\) (BTO) membrane with monolayer MoSe\(_2\) in a dual gate device that enables in-situ manipulation of the BTO ferroelectric polarization with a voltage pulse. While two-dimensional (2D) transition metal dichalcogenides (TMDs) offer remarkable adapta...
