摘要
We have attempted to predict a certain amount of boron concentration in boron-doped CVD diamond single crystals by Raman spectroscopy. The asymmetrical feature was observed on one-phonon Raman line shape of B-doped diamond. The feature is depended on the boron concentration. We performed Fano line fitting for one-phonon line. Fano parameters represented the asymmetry of one-phonon line. The relation between Fano parameters and boron concentrations obtained in this study can estimate a certain amount of boron concentration of B-doped diamond crystals.
