Simulation Field Effect Transistor Bipolar Graphene Nano-ribbon
The purpose of this paper is to use software package ATK-SE package, in combination with virtual Nano-Lab (VNL), can be used to investigate a Nano-scale transistor. For the transistor structure we will use a graphene junction device, where ATK is used to investigate the properties of a similar system. The effect of various parameters on the structure of graphene Nano-ribbon checked. It consists of 3 regions and forms a metal-semiconductor-metal junction. By applying a gate potential to the central region, the system can function as a field effect transistor, which is able to calculate properties, Transmission spectrum, Temperature dependent conductance, Conductance and Current as function of gate potential and temperature. So in this paper, the device design and simulation parameters are associated with improved performance.
