Title: Edge structure of epitaxial graphene islands
Published: June 07, 2010
Abstract: Graphene islands grown epitaxially on 6H-SiC(0001) were studied using scanning tunneling microscopy and spectroscopy. Under specific growth conditions, {approzimately equal}10 nm single-layer graphene islands are observed on top of the SiC buffer layer and align with the SiC(0001)-1X1 lattice directions. Atomic-resolution images show that the edges of the island closely follow an armchair-edge configuration.
