Abstract

Diamond nanoparticles grown previously by Hot Filament Assisted Chemical Vapor Deposition have been characterized by utilizing Atomic Force Microscopy, Scanning Electron Microscopy, Raman Spectroscopy and X Ray Diffraction. AFM and SEM data shows increase in nanoparticle size with growth period ranging from about 20 nm for 15 minutes to 200 nm for 105 minutes growth. Raman spectra have been analyzed by using optical phonon confinement in nanometer size crystals. Based on the SEM, Raman spectroscopy and XRD data, we present clear evidence for nanometer size (10-200 nm) diamond particles in CVD-grown diamond thin films.
