# 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
