A non-volatile memory device consisting of graphene oxide covalently functionalized with ionic liquid

Abstract

We introduce non-volatile resistive crossbar memory based on ionic liquid covalently functionalized on a partially reduced graphene oxide (PrGO). The write-read-erase-read (WRER) cycles were very stable after several hundred cycles and the retention time of both the ON and OFF states was stable for over 1000 s, indicating that the device we developed can function as a non-volatile memory device.
