# DATE: 2016-12-21 UNITS: metal CONTRIBUTOR: Sayyed Jalil Mahdizadh, saja.mahdizadeh@gmail.com CITATION: Mahdizadeh, Akhlamadi, J. Mol. Graph. Model. 72, 1-5 (2017)
# 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
