Abstract

A selector device may include a first electrode, a tunneling layer, and a ferroelectric layer. The tunneling layer may be between the first electrode and the ferroelectric layer, and a thickness and dielectric constant of the tunneling layer relative to a thickness and dielectric constant of the ferroelectric layer may cause a depolarizing electric field induced in the first tunneling layer to be greater than or approximately equal to an electric field induced in an opposite direction by ferroelectric dipoles in the ferroelectric layer when a voltage is applied across the selector device. The device may also include a second electrode, and the ferroelectric layer may be between the tunneling layer and the second electrode. A seconding layer may also be added between the ferroelectric layer and the second electrode for bipolar selectors.
