A semiempirical quantum mechanical (MNDO) method was applied to investigate the energetics of a recently proposed elementary-reaction mechanism of epitaxial diamond growth at low pressures. The mechanism consists of surface activation by H atom abstraction of a hydrogen atom from a surface carbon followed by the addition of acetylene molecules. The computed potential surface indicated that the propagation steps, those of acetylene addition, proceed without any energy barriers.
