Abstract

Density functional theory with non-equilibrium Green's function has been used to extract the current voltage behaviour, fermi velocities and dynamical parameters of Oxygen (O) doped Zigzag Graphene Nano ribbons (GNRs). The Zigzag GNR has been subjected to monovacancy, and decorated with oxygen impurities at three possible sites around the Monovacancy (MV). The transport properties of these structures have been analysed in terms of transmission spectrum, I- V characteristics, transmission pathways and the dynamical parameters (kinetic inductance and quantum capacitance) of oxygen decorated ZGNRs. It has been observed that both linear I- V characteristics and improved dynamical parameters of 20- MVZGNR are relatively suitable for interconnect application in comparison to its other counterparts.
