Monte Carlo (MC) simulation is carried out to study solidification of Si by
a BCC lattice-gas model. To describe actual Si phases as quantitatively as
possible, the Tersoff Si potential is mapped onto the BCC model by using t
he potential renormalization technique proposed by one of us. Using the ren
ormalized potential, thermal properties are obtained for four plausible Si
structures. The solidification process is studied by MC simulation. It is s
hown that calculation of the thermal properties of Si is greatly improved b
y using the lattice model with a renormalized potential. (C) 2001 Elsevier
