By chemical vapor deposition, we have tried to grow epitaxial films of graphene nano-ribbons on Pt (755) and TiC (755) surfaces. Some properties of these graphene films have been clarified by X-ray photoelectron spectroscopy, low energy electron diffraction, and angle-resolved ultraviolet photoelectron spectroscopy. Nano-ribbons have not been prepared on Pt (755), but they have successfully been prepared on TiC (755). Quantized n bands and new electronic states at E, have been found in the photoemission spectra.
