Study the effect of applied voltage on propagation delay of bilayer graphene nanoribbon transistor

Fundamental limitations of CMOS technology and anticipations of Moore's law have motivated researchers to find several alternatives for these devices such as nanowire, carbon nanotube and graphene nanoribbon. In this work firstly, we develop an analytical model for quantum capacitance of monolayer and bilayer graphene. Secondly, resistance of the channel is modelled based on conductance of the nanoribbon and finally propagation delay is calculated by using resistance and capacitance.
