Diamond by CVD (chemical vapour deposition) is formed as crystals or as films from various gaseous hydrocarbons or other organic molecules in the presence of activated, atomic hydrogen. It consists of sp3-hybridized carbon atoms with the three-dimensional crystalline structure of the diamond lattice.
Note:
'CVD @D01671@' or 'low-pressure diamond' are synonyms of the term @D01671@ by CVD. @D01671@ by CVD can be prepared in a variety of ways. Deposition parameters are: total (low) pressure, partial hydrogen pressure, precursor molecules in the gas phase, temperature for @A00093@ of the hydrogen and that of the surface of the underlying substrate. The energy supply for the hydrogen @A00093@ may be, for instance: heat, radio frequency, microwave excitation (plasma deposition) or accelerated ions (e.g. Ar+ ions). CVD @D01671@ has also been obtained at atmospheric pressure from oxyacetylene torches and by other flame-based methods. Often CVD carbon films consist of a mixture of sp2- and sp3‑hybridized carbon atoms and do not have the three-dimensional structure of the @D01671@ lattice. In this case they should be called @H02741@ or @D01673@.
