Abstract

In this study, the metastable state diamond thin films have been deposited on Si substrates from methand-hydrogen and oxygen mixture usin gMicrowave Plasma Enhanced Chemical Vapor Deposition (MWPCVD) method. effects experimental parameters MWPCVD including methan concentrations, oxygen additions, operating pressure, deposition time on the growth rate and crystallinity were investigated. diamond thin film was synthesized under the following conditions: methane concentration of 0.5%(0.5sccm)∼5%(5sccm). oxygen concentration of 0∼80%(2.4sccm). operating pressure of 30Torr∼ 70Torr, deposition time of 1∼32hr. SEM, WRD, and Raman spectroscopy were employed to analyse the growth rate and morphology, crystallinity and prefered growth direction, and relative amounts of diamond and non=diamond phases respectively.
