We report the fabrication of nanocrystalline graphite films on sapphire substrates of various cutting directions by using solid carbon source molecular beam epitaxy. Raman spectra show a systematic change from amorphous carbon to nanocrystalline graphite with a cluster diameter of several nanometers...
