Yl. Kuang et al., SURFACE-STRUCTURE OF HOMOEPITAXIAL DIAMOND(001) FILMS, A SCANNING-TUNNELING-MICROSCOPY STUDY, Applied physics letters, 67(25), 1995, pp. 3721-3723
The surface structures of homoepitaxial diamond(001) films have been s
tudied by using scanning tunneling microscopy. Boron-doped films were
grown on natural diamond substrates. Images showed a dimer-type 2x1 re
construction with well-resolved dimers. The surface consists of altern
ating terraces of 2 x 1 and 1 x 2 dimerization which are separated by
single-layer steps with inequivalent step edges along [110] directions
. Double-layer steps running parallel to dimer rows of the upper terra
ces were observed locally. We have also observed local 3 x 1 configura
tions, antiphase boundaries, and dimer vacancies, etc. (C) 1995 Americ
