摘要
The light scattering properties of superconducting (Tc?similar to 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. Lineshape analysis reveals Fano lineshapes with a significant asymmetry (q similar to-2). An anomalous wavelength dependence and small value of the Raman scattering amplitude is observed in agreement with previous studies.
