Abstract

Nucleation of diamond crystal is observed on a surface of fine diamond particles of micron meters attached to a nickel plate placed in methane-hydrogen plasma. The electron temperature T_e in the plasma is quite important for the nucleation. When T_e is reduced to ∼0.4 eV, we observed an appearance of nanometer diamond nucleation on the surface of the fine diamond particles. The size and the number of nucleation cite increase with the deposition time with average growth rate of ∼10 nm/h.
