A Study of the Structural and Vibrational Properties of Diamond Nanoparticles Grown by Chemical Vapor Deposition

Abstract:

Article Preview

Diamond nanoparticles (NPs), grown by chemical vapor deposition (CVD), have been characterized by utilizing AFM, SEM, and Raman spectroscopy. AFM and SEM data show increase in NPs size with growth period, ranging from about 20 nm for 15 min to 200 nm for 105 min growth. The Raman spectra show a sharp line at around 1332 cm-1, which is characteristic of diamond structure. We analyze the Raman spectra by using optical phonon confinement in nm-size crystals and discuss the resulting data for NP sizes.
