Resumo |
Diamond films were prepared by microwave plasma chemical vapor deposition (MWPCVD). In order to obtain better field emission properties, the samples coated with different metals were prepared. The results showed that the field emission properties of diamond coated with metals could be greatly improved in comparison to pure diamond film and the different kinds of coated metals have different influences on the field emission properties. The possible reasons of effects on the field emission properties are discussed, which were probably due to the reduced effective surface work function by metal coatings; but the detail of the mechanism should be studied further. The surface morphology and microstructure of the sample were characterized by Atomic Force Microscope (AFM), X-ray photoelectron spectroscopy (XPS), X-ray Diffraction (XRD) and Raman spectrum tests.
