Description
Summary:Heavily boron doped nanocrystalline diamond films grown on glass substrates by the method of plasma-chemical deposition, were investigated using Raman spectroscopy. Analysis of the spectra showed both the phonon confinement effect in nanocrystalline grains and Fano interference effect due to the contribution of electron Raman scattering in heavily doped p-type diamond films. The increase of boron concentration led to decrease of the size of crystalline diamond grains. The films are semitransparent and have good conductivity, so that it can be used as transparent electrodes in giant-scale electronics and optoelectronics. •Raman scattering in heavily doped p-type diamond films showed both the phonon confinement effect in nanocrystals and Fano interference.•Increase of boron concentration in doped nanocrystalline diamond films grown by the method of plasma-chemical deposition led to decrease of the size of crystalline diamond grains.
