Abstract

By chemical vapor deposition, we have grown monolayer epitaxial films of graphite nano-crystals and graphite nano-ribbons on TiC (111)-facet surface and TiC (410) surface, respectively. Some properties of these graphite monolayer films have been studied by X-ray photoelectron spectroscopy (XPS), low energy electron diffraction (LEED) and angle-resolved ultraviolet photoelectron spectroscopy (ARUPS). The graphite nano-films have been successfully prepared by ethylene exposure of 6×105 L on the TiC (111)-facet surface at 1250°C, and the nano-ribbons by 2×104 L on the TiC (410) surface at-1050°C.
