Basics of low pressure diamond deposition

Production of atomic hydrogen and transport to the substrate surface is necessary.
Selective etching of graphite by atomic hydrogen allows the growth of diamond.
For diamond growth it is necessary to use an adequate atomic hydrogen to carbon ratio.

Diamond deposition methods

The atomic hydrogen can be produced by thermal or plasma decomposition of atomic hydrogen.

Diamond nucleation and growth

The diamond nucleation is influenced by the substrate material, substrate surface treatment, and deposition parameters.

Morphologies and microstructures

Influences of impurities during diamond growth

Diamond applications

  • wear parts - cutting tools, drills ...
  • heat sinks
  • optical parts - windows, lenses ...
  • electrodes - electrochemistry
