# 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
