Measurement of power consumption in graphene based logic gate for incident angle variation

Graphene is assumed that it can be used in analog electronics because of its extraordinary electronic features. But nowadays it is investigated in digital logic gates due to the tunability of Fermi energy level. For making a promising logic gate, graphene is now exercised in correlation with the using of optics law. Transport properties in a doped graphene are extensively determined by measurement of incident angle. From which an important property of a device like “resistance of interface” can be extracted. Moreover, width of the graphene is one of the issues to be thought. By minimizing resistance of interface and maximizing the width of graphene, considerable power consumption can also be determined. In this paper, we will observe the electron transmission probability depending on the variation of incident angle of light of an interface. Then, we will calculate the resistance of interface. We will investigate the ambipolar characteristics by observing dc conductivity of graphene. At last, we will measure the power consumption of the device by tradeoff between the resistance and width of graphene.
