Diamond films with various surface morphologies were obtained
which were deposited on pretreated molybdenum by microwave plasma-assisted chemical vapor deposition system. The films were characterised by X-ray diffraction (XRD)
Raman spectrum
optical microscopy and scanning electron microscopy(SEM). The result of expe riment indicates that diamond films with ball-like graphitic surface morohologis
which consisted of diamond nulei
were obtained. By investigating electron emission of the diamond-amorphous carbon films
we found that the lower of the size of the ball-like graphitics in diamond-amorphous carbon thin films the most efficient of electron emission.
