Abstract

In this tool, a novel reconfigurable graphene routing device based on p-n junctions can be simulated. In this routing device, switching is accomplished by using co-planar split gates that modulate the properties that are unique to graphene, including ambipolar conduction, electrostatic doping, and angular dependent carrier reflection. In addition, the use of these control gates can dynamically change the operation of the device, leading to reconfigurable routing device. A device model is derived from carrier transmission probability across the p-n junction for allowing quantitative comparison to CMOS logic.

The simulation tool is build based on this model and it can estimate on/off resistances and the capacitance of the electrostatic gates. Based on the RC values, the area, delay and power performance analyses are carried out. Moreover, a current-voltage characteristic curve of the p-n junction is calculated.
