Engineering the band structure and magnetism in edge corrugated zigzag graphene nanoribbons — •Prakash Parida1 and Swapan K Pati2 — 1Institute for Theoretical Physics, University of Regensburg, D-93040 Regensburg, Germany — 2Theoretical Sciences Unit, Jawaharlal Nehru Centre For Advanced Scientific Research, Bangalore 560064, India
Electronic structure and conductance properties of edge-corrugated zigzag graphene nanoribbons have been studied within the framework of p-orbital tight binding model with a mean field approximation to the Hubbard term. The results show that, both the band gap and magnetic moment increase with the depth of corrugation. Electric field modulates the carrier nature of mid-gap states to a great extent.
