# DATE: 2010-08-16 UNITS: metal CONTRIBUTOR: Teodoro Laino, teodoro.laino@gmail.com CITATION: S. Mumetoh et al, Comp Mat Sci, 39, 334-339 (2007)
# Tersoff parameters for various elements and mixtures
# multiple entries can be added to this file, LAMMPS reads the ones it needs
# these entries are in LAMMPS "metal" units:
# A,B = eV; lambda1,lambda2,lambda3 = 1/Angstroms; R,D = Angstroms
# other quantities are unitless
# This is the SiO parameterization from a particular Tersoff paper:
# S. Mumetoh et al., Comp. Mat. Sci., 39 (2007) 334-339
# converted to LAMMPS format on 08.2010
# Teodoro Laino, teodoro.laino@gmail.com
# format of a single entry (one or more lines):
# element 1, element 2, element 3,
# m, gamma, lambda3, c, d, costheta0,
# n, beta, lambda2, B, R, D, lambda1, A
