Mumetoh et al, Comp Mat Sci, 39, 334-339 (2007) # 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 SiO parameterization from a particular Tersoff paper: # S. Mumetoh et al., Comp. Mat. Sci., 39 (2007) 334-339 # converted to LAMMPS format on 08.2010 # Teodoro Laino, teodoro.laino@gmail.com # 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 Si Si Si 3.0 1.0 0.0 100390 16.217 -.59825 0.78734 0.0000011 1.73222 471.18 2.65 0.15 2.4799 1830.8 Si Si O 3.0 1.0 0.0 100390 16.217 -.59825 0.00000 0.0000000 0.0000 000.00 2.215 0.155 0.0000 0000.0 Si O Si 3.0 1.0 0.0 100390 16.217 -.59825 0.00000 0.0000000 0.0000 000.00 2.65 0.15 0.0000 0000.0 Si O O 3.0 1.0 0.0 100390 16.217 -.59825 0.78734 0.0000011 2.04456 378.690 2.215 0.155 3.32549 1856.495 O Si Si 3.0 1.0 0.0 64692.1 4.11127 -.845922 1.04968 0.00000011632 2.04456 378.690 2.215 0.155 3.32549 1856.495 O Si O 3.0 1.0 0.0 64692.1 4.11127 -.845922 0.00000 0.0000000 0.0000 000.00 1.85 0.15 0.0000 0000.0 O O Si 3.0 1.0 0.0 64692.1 4.11127 -.845922 0.00000 0.0000000 0.0000 000.00 2.215 0.155 0.0000 0000.0 O O O 3.0 1.0 0.0 64692.1 4.11127 -.845922 1.04968 0.00000011632 2.35692 218.787 1.85 0.15 4.17108 1882.55
