Novel Circuit Design Methodology with Graphene Nanoribbon Based Devices

Graphene has attracted a high amount of interest in recent years in many research fields, including the field of electronics. Due to its spectacular properties, it is investigated as a candidate material for the realization of nanodevices that will constitute conventional or even unconventional computing circuits. In this work, we explore the ability of Graphene Nanoribbon based topologies to create a universal computing set. We propose the design of an AND, OR and NOT gate, as well as the design of a Buffer, for the first time in a configuration similar to the Pass Transistor Logic (PTL) configuration. The valid operation of the proposed topologies is verified through accurate SPICE simulations, providing the ability to design combinational logic using Graphene, based on PTL methodology.
