Graphene Ferroelectric Device and Opto-Electronic Control of Graphene Ferroelectric Memory Device

摘要

In accordance with an embodiment of the invention, there is provided a graphene ferroelectric device. The device comprises a graphene transistor channel and a ferroelectric gate of the graphene transistor channel, the ferroelectric gate comprising a linear polarization at a first applied gate voltage less than a threshold voltage, and a hysteretic polarization at a second applied gate voltage greater than the threshold voltage. The device may be configured to undergo optical switching of the graphene transistor channel between a high resistance state and a low resistance state in response to photoillumination of the device.
