摘要：

The ab initio quantum chemistry program KGNMOL-89 was used to study the cleavage of silicon and germanium clusters in the diamond structure. The potential energy of stretching and shearing planes with three bonds per atom (glide planes) increases much faster than for planes with single bonds (shuffle planes). The cleavage process is discussed and it is shown how glide-plane cleavage can occur, with consequences for surface structure models.
