In this paper, we introduce a novel reconfigurable graphene logic based on p-n junctions. device, switching is accomplished by using co-planar split gates that modulate the properties are unique to graphene, including ambipolar conduction, electrostatic doping, and angular dependent carrier reflection. addition, use of these control can dynamically change operation leading multi-functional logic. A device model derived from transmission probability across junction for allowing quantitative comparison CMOS Based model, show proposed has significant advantages over gate in terms delay-power product signal restoration, while maintaining similar footprint. Furthermore, utilizes large sheet with minimal patterning, feasible integration circuits, potential CMOS-graphene hybrid circuits.
