Fabrication of titanium oxide memristors with platinum andgraphene top electrodes

In recent years, extensive research has been conducted on memristors, which are promising and non-volatile memory devices that effectively mimic biological synapses. The application of graphene as the top electrode in memory switching systems offers an interesting alternative to traditional materials. Graphene, a carbon- based material, possesses remarkable attributes such as a high surface-to-volume ratio, biocompatibility, exceptional adsorption capabilities, and excellent electrical conductivity, making it a promising avenue for the production of biosensors with desired properties. Within this scope, a study has been conducted on the fabrication of both a traditional memristor structure and a memristor structure with a graphene top electrode. The traditional structure was produced with a focus on modeling and circuitry applications, while the graphene top electrode structure was motivated by the desire to obtain sensors by harnessing the properties of graphene and memristors. Innovative fabrication methodology involving patterning of synthesized and transferred graphene was employed in the production of micro devices with graphene top electrodes. Fabrication of memristive devices was successfully accomplished using techniques such as electron beam evaporation, photolithography, and sputtering on a silicon wafer.
