# DATE: 2011-05-03 CONTRIBUTOR: Aidan Thompson, athomps@sandia.gov CITATION: Tersoff, Phys Rev B, 49, 16349 (1994)

# Si and C mixture, parameterized for Tersoff potential
# this file is from Saurav Goel - sg258@hw.ac.uk
# J. Tersoff, Phys. Rev. B, 49, 16349 (1994).

# 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

# 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

# Tersoff's nomenclature -	-	-	c	d	  h		n	beta		mu	B	R = (R+S)/2  D = (S-R)/2  Lambda    A
