TER ratio as a function of the magnitude of P in. Arrows represent the direction of pinned interface dipole which is assumed to be preassigned. The horizontal dashed line stands for the case that the interface is replaced by an SrTiO3 monolayer, and the horizontal dotted line represents the case that the interface is replaced by a BaTiO3 monolayer.
