Mathematical Model of Transmission Coefficient in Bilayer Graphene Nanoribbons

Graphene is characterized with amazing carrier transport property and high sensitivity at the single molecule level, making them great as resources used in Nano electronic applications. Bilayer graphene nanoribbons consist of two monolayers graphene stacked in two possible configurations. Bilayer graphene nanoribbons can be employed in digital electronics because its band gap can be varied by means of an external perpendicular electric field, and can induce a significant band gap between the valence and conduction bands turning it from a zero-gap semiconductor to an insulator. The present research models transmission coefficient of the Schotcky structure in the graphene-based transistor based on semiconducting channel width and then analysis its quantum properties given dependence on structural parameter.
