“…The DOS spectrum provides the perception of the charge in the measured area. It will give information about density of the charge within the energy interval [5]. In this research work, the voltage across the two electrodes and the nanoribbon is varied within the interval of 0 -1 V. Here the Fermi level is zero.…”

This study investigates the roles of the edge and substrate effects of zigzag and armchair graphene nanoribbons on atomic and electronic structures of graphene. Graphene is a two-dimensional flat monolayer of carbon atoms packed into a honeycomb lattice. It is made out of carbon atoms arranged in hexagonal structure. Graphene has a high electronic mobility and high charge carrier concentrations. Series of simulations with Zigzag and Armchair nanoribbons are made using Gold, Copper, and Indium. The electronelectron interactions of the nanoribbons' molecules are calculated with generalized gradient approximation (GGA) through Perdew-Burke-Ernzerhof (PBE) exchange correlation. The k-points are set to 1 x 1 x 50 for na, nb, and nc, respectively. The electron temperature of 300K is used. The CC bond length between the carbon atoms in graphene nanoribbon is 1.24 Å. The superposition of the various orbitals in the nanoribbon leads to the variation in the Density of States (DOS). The Projected Density of States (PDOS) on the edge is mainly consistent around Fermi level. Electron Density calculations show regions with large electron density, which are found around the atoms, and their bonds. The observed nanotubes may have great potential for the application in nanoscale electronic devices fabrication and can be used as gate in the FET transistors.
