Abstract

In this paper, a theoretical study on the optical and electrical properties of bilayer graphene is presented. Graphene with a single atomic layer of carbon and outstanding optical properties is an ideal nominee on sensor application because of high surface-to-volume ratio. In this report optical properties of bilayer graphene nanoribbon (BGN) in the presence of applied bias for different incident wavelength are explored. (BGN) dielectric constant and refractive index based on its conductance are modeled theoretically and obtained results are simulated numerically. Based on the presented model applied bias effect on BGN optical parameters are discussed.
These results are relevant for applications of recently developed graphene based devices in advanced optoelectronics such as surface plasmon resonance sensors.
