CRESTED BARRIER DEVICE AND SYNAPTIC ELEMENT

Abstract:

A crested barrier memory and selector device may include a first electrode, a first self-rectifying, tunneling layer having a first dielectric constant, and an active, barrier layer that has a second dielectric constant and another self-rectifying, tunneling layer having a third dielectric constant. The first self-rectifying layer may be between the first electrode and the active layer. The second dielectric constant may be at least 1.5 times larger than the first dielectric constant. The device may also include a second electrode, where the active, barrier layer is between the first self-rectifying, tunneling layer and the second electrode.
