Abstract

Atomic images of epitaxial (100) diamond were obtained in ultrahigh vacuum (UHV) with a scanning tunneling microscope (STM). The dimer row spacing, inner dimer pair, and single atomic step height were measured to be 0.5 nm, 0.25 nm and 0.1 nm respectively. Different forms of amorphous carbon were also observed in UHV. Some forms appeared to be randomly oriented others appeared chain-like. A radial reconstruction 1.5 nm in diameter was found on a 20° slope to a group of (100) 2x1 reconstructions. Current vs voltage spectrum was obtained in UHV and showed the electronic characteristics of the film. The Raman spectrum of the diamond film showed sp2 and sp3 peaks.
