Study of crystallographic orientations in the diamond film on the (100) surface of cubic boron nitride using a Raman microprobe

We have measured Raman spectra of a diamond film prepared on the (100) surface of cubic boron nitride(c‐BN) by the dc plasma chemical vapor deposition method. It is found that the polarization property of the Raman line of diamond coincides well with that of the LO phonon for the (100) surface of c‐BN. The coincidence between the polarization property of Raman lines of diamond and c‐BN evidences heteroepitaxial growth of the diamond film on the (100) surface of c‐BN.
