Armchair Graphene Nanoribbon Photonics

Abstract

Graphene based nanomaterial ushering a tremendous outburst of scientific activity in the study of electronic and photonic properties. Nano sized ribbon of monolayer graphene named graphene nanoribbon has born to demonstrate as a semiconducting behavior in electronic branch of science. Today's GNR start its journey to photonic science which is a curiosity to the naive scientist of nanotechnology. In this paper we have integrated electronic and photonic properties to observe the photonic behavior of GNR. Here we have used one materials of GNR shows semiconducting behavior which is named as armchair GNR (A-GNR). We will calculate a definite band gap energy and width of A-GNR from its geometrical structure for a particular free space optical wavelength. Then by using these two parameter we will observe the carrier concentration, electronic conductivity and sheet resistance considering thermal effect. Then we will measure the optical conductivity. The photonic properties which will be investigated then by using these above parameter. Upon calculating the transmittance we will approach a decision that for which condition the device will be more transparent whether it will be indistinct.
