Nucleation and Growth Processes During The Chemical Vapor Deposition of Diamond

Abstract

ABSTRACTThe nucleation of independent diamond crystals can occur through graphitic, sp2, intermediates. Evidence from several sources indicates that diamond growth may take place through sp2 surface layers. Steady state analysis of simple reaction networks leads to expressions for the diamond growth rates, the concentration of sp2 impurities in the diamond, and for the nucleation rate of new crystals.
