# 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 Ge reparameterization from the following paper:
# Optimized  Tersoff  empirical  potential for germanene
# Mahdizadeh, Akhlamadi, J. Mol. Graph. Model. 72, 1-5 (2017)

# 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
