LAYERED CAPACITOR DEVICE WITH CHARGE BLOCKING LAYERS

摘要

A multi-layered capacitor device is provided in which the multi-layered capacitor device includes a metal or metal-oxide ground electrode, a capacitor dielectric layer, a metal or metal-oxide top electrode, a hole blocking layer and an electron blocking layer . The hole blocking layer is located at the interface of the metal or metal-oxide ground electrode and the capacitor dielectric layer to increases the effective barrier height at the interface. The electron blocking layer is located at the interface of the metal or metal-oxide top electrode and the capacitor dielectric layer to increases the effective barrier height at the interface.
