Memristors based on graphene is a promising alternative to contemporary field-effect transistor (FET) technology achieves higher integration density and lower power consumption. The use of graphene as electrodes in memristors could also increase robustness against degradation mechanisms. To realize this researchers in the UK have developed a process for direct growth of high-quality monolayer graphene on sapphire wafers in a mass-producible, contamination-free, and transfer-free manner using a commercially available metal–organic chemical vapor deposition (MOCVD) system. Using their process they developed graphene-electrode based memristors incorporating graphene electrodes at wafer scale. The memristor demonstrated promising characteristics in terms of endurance, retention, and ON/OFF ratio. According to the researchers their work presents a possible and viable route to achieving robust graphene-based memristors in a commercially and technologically sustainable manner, paving the way for the realization of more powerful and compact integrated graphene electronics in the future… read more.
