Memtransistors Based on Nanopatterned Graphene Ferroelectric Field-Effect Transistors

Abstract

The ultimate memristor, which acts as resistive memory and an artificial neural synapse, is made from a single atomic layer. In this manuscript, we present experimental evidence of the memristive properties of a nanopatterned ferroelectric graphene field-effect transistor (FET). The graphene FET has, as a channel, a graphene monolayer transferred onto an HfO2-based ferroelectric material, the channel being nanopatterned with an array of holes with a diameter of 20 nm.
