Nano-graphite films have been deposited on n-Si substrates by microwave plasma chemical vapour deposition. The surface morphology and microstructure of the films were tested by scanning electron microscopy, x-ray diffraction and Raman spectroscopy. In the field emission measurement, a tu-on field of 0. 5 V/μm and a high emission-site density of 105/cm2 on a tested emission area of (34 × 35 mm2) have been obtained.
