# 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 Si parameterization from a particular Tersoff paper:
|
|
# J. Tersoff, PRB, 37, 6991 (1988)
|
|
# See the SiCGe.tersoff file for different Si variants.
|
|
|
|
# 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
