The spectral depth profiles of heteroepitaxial diamond showed the diamond peak at 1332-1335 cm-1 and four bands centered at 1230 cm-1, 1470-1490 cm-1, 1530-1580 cm-1, and 1640 cm-1 near the surface. The diamond peak shifted to the single crystal peak position at 1332 cm-1 as the linewidth was broadened with free surface proximity. The compressive strain in the heteroepitaxial diamond crystal decreased and turned into the random strain. At the same time, the Raman band at 1470-1490 cm-1 grew in intensity. The constituents of non-diamond phase in the heteroepitaxial growth regions are different from those formed in the randomly oriented regions.
