The raman spectrum of nanocrystalline diamond
Webb24 apr. 2012 · The light scattering properties of superconducting (Tc=3.8 K) heavily boron doped nanocrystalline diamond has been investigated by Raman spectroscopy using visible excitations. Fano type interference of the zone-center phonon line and the electronic continuum was identified. Webband Raman characteristics of boron-doped c-NCD films. Studies of the Raman spectra from B-doped diamond films have also been restricted almost exclusively to epitaxial or MCD films [13]. The diamond phonon observed at 1332 cm-1 is a symmetric Lorentzian at low boron concentration, but as the boron concentration increases
