ABSTRACT
There is no experimental evidence for very small clusters (< 2 nm)
with the Td symmetry (Lamport, 1987). From a theoretical point of
view adamantane Si clusters can be built up by saturation of the
dangling bonds with hydrogen. Generally speaking, Silicon hydride
clusters labeled SiNHM grow from the decomposition of silane gas
prior a nucleation growth (Watanabe et al., 1997).
