  • HF CVD diamond nucleation and growth on

    2008-1-15 · Conversely, it has been shown that diamond nucleation on monocrystalline Cu(111) occurs from graphitic basal planes . It is expected that the diamond nucleation occurs on this carbon top layer, leading to randomly-oriented nuclei. If true, diamond nucleation is the result of a pure carbon phase transformation during HF CVD process.
