Observation of the nanoscale epitaxial growth of diamond on Si (100) surface

Abstract
Epitaxial growth of noncrystalline diamond thin film on Si(001) surface has been observed using high-resolution transmission electron microscopy. The epitaxial lattice relationship at diamond/Si interface has been described based on a cube-cube orientation with a≊7° tilt plus a rotation of the diamond lattice from the substrate lattice. The observed epitaxial behavior can be explained by the 3:2 lattice coincidence and the introduction of interfacial misfit dislocations.
