Abstract: We have investigated an origin of the superconductivity discovered in boron (B)-doped diamonds by means of -NMR on heteroepitaxially grown and films and polycrystalline film. The characteristic difference of B-NMR spectral shape for the and thin films is demonstrated as arising from the difference in the concentration of boron substituted for carbon. It is revealed from a scaling between a superconducting transition temperature and that the holes doped into diamond via the substitution of boron for carbon are responsible for the onset of superconductivity. The result suggests that the superconductivity in boron-doped diamond is mediated by the electron–phonon interaction brought about a high Debye temperature characteristic for the diamond structure.
