Heteroepitaxial diamond growth on platinum(111) by Shintani process

Diamond films were grown on single crystal platinum bulk and films with(111) surface by microwave plasma chemical vapor deposition. It was observed by scanning electron microscopy (SEM) that, in both cases, many of the neighboring facets coalesced with each other. X-ray diffraction analyses revealed that the (111) planes of the diamond films were parallel to the substrate surface and azimuthally oriented. The early stage of diamond growth was observed by SEM and it was found that positional and orientational changes of diamond particles occur on the platinum surface.
