# DATE: 2013-03-21 UNITS: metal CONTRIBUTOR: Cem Sevik CITATION: Kinaci, Haskins, Sevik and Cagin,  Phys Rev B, 86, 115410 (2012) 
# Tersoff parameters for B, C, and BN-C hybrid based graphene like nano structures
# 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

# Cem Sevik (csevik at anadolu.edu.tr) takes full blame for this
# file.  It specifies B-N, B-C, and N-C interaction parameters 
# generated and published by the reseacrh group of Prof. Tahir Cagin.

# 1. Physical Review B 84, 085409 2011
#    Characterization of thermal transport in low-dimensional boron nitride nanostructures, 
#

# 2. Physical Review B 86, 075403 2012
#    Influence of disorder on thermal transport properties of boron nitride nanostructures
#

# 3. Physical Review B 86, 075403 2012, Please see for further information about B-C and N-C parameters
#    Thermal conductivity of BN-C nanostructures
#

# The file also specifies C-C, interaction parameters 
# generated and published by the reseacrh group of Dr. D. A. Broido
# Physical Review B 81, 205441 2010
# Optimized Tersoff and Brenner empirical potential parameters for 
# lattice dynamics and phonon thermal transport in carbon nanotubes and graphene

# Users in referring the full parameters can cite the full parameter paper (3) as:
#      A. Kinaci, J. B. Haskins, C. Sevik, T. Cagin,  Physical Review B 86, 115410 (2012) 
#      Thermal conductivity of BN-C nanostructures
