11. Effects of magnetism and electric field on the energy gap of bilayer graphene nanoflakes
Topic: Nanophysics
Published: 1/13/2010
Author: Hongki Min
Abstract: We study the effect of magnetism and perpendicular external electric field strengths on the energy gap of length confined bilayer graphene nanoribbons (or nanobars) using a first principles density functional electronic structure method and a semi-lo ...

12. Origin of Universal Optical Conductivity and Optical Stacking Sequence Identification in Multilayer Graphene
Topic: Nanophysics
Published: 8/6/2009
Authors: Hongki Min, Allan H. MacDonald
Abstract: We predict that the optical conductivity of normal graphene multilayers is close to {sigma}^duni^=({pi}/2) e^u2^/h per layer over a broad range of frequencies. The origin of this behavior is an emergent chiral symmetry which is present in normal N-l ...
