This article presents novel analysis of the characteristic Raman spectrum of heavily boron-doped diamond based on the study of the large amount of Raman spectra available in the literature. This analysis shows that the shift and the broadening of the diamond Raman peak results from the Fano and phonon confinement effects due to the high concentration of boron impurities. This method opens the road for determination of atomic boron concentration in diamond by simple and non-destructive Raman characterization.
