Abstract

Diamond films have been synthesized by microwave Plasma Enhanced CVD (PECVD) and permanent magnet induced Electron Cyclotron Resonance (ECR) PECVD of hydrogen diluted methane. The films are characterized by SEM images and Raman spectroscopy. The diamond films grown by ECR-PECVD show clear-cut habits of cubic crystal in SEM images, while the film grown by microwave PECVD are the polycrystalline. A Raman line at 1333cm‒1 and broad band located at ∼1500 cm‒1 were obtained for the films grown by both methods. However, the film grown by microwave PECVD shows a larger broad band which is associated with an sp2-bonded graphitic phase
