Abstract: Diamond films were deposited on Al2O3 substrates by microwave plasma chemical vapor deposition (MPCVD) and hot filament chemical vapor deposition (HFCVD) techniques, respectively. The qualities of the deposited films were characterized by scanning electron microscopy(SEM), X ray diffractive spectrometry and Raman scattering spectrometry. The dielectric properties of the diamond film/alumina composites were measured and analyzed as well.

Key words: diamond, thin film, alumina ceramics, dielectric properties
