Epitaxial graphene films grown on silicon carbide (SiC) substrate by solid state graphitization is of great interest for electronic and optoelectronic applications. In this paper, we explore the properties of epitaxial graphene films on 3C-SiC(111)/Si(111) substrate. X-ray photoelectron spectroscopy and scanning tunneling microscopy were extensively used to characterize the quality of the few-layer graphene (FLG) surface. The Raman spectroscopy studies were useful in confirming the graphitic composition and measuring the thickness of the FLG samples.

    Here, we report direct experimental evidence for the presence of flat bands, close to the Fermi level, in one-dimensional topological defects of graphite. The flat bands are manifested by a pronounced peak in the tunnelling density of states. Our ab initio calculations indicate that the flat...
