Abstract
Disclosed are energy efficient ferroelectric devices and methods for making such devices. For example, a ferroelectric device may be a ferroelectric tunneling junction device that includes a graphene layer on a substrate. A tunneling layer may be disposed on a portion of the graphene layer. The tunneling layer may be a ferroelectric material. A metal electrical contact layer may be disposed over the tunneling layer and the graphene layer. Additionally, some embodiments may have an additional monolayer disposed between the tunneling layer and graphene layer. By specific engineering of such layers, tunneling electroresistance performance may be substantially improved.
