摘要: A new parametrization of the anisotropic interlayer potential for hexagonal boron nitride (h-BN ILP) is presented. The force-field benchmarked against density functional theory calculations several dimer systems within Heyd-Scuseria-Ernzerhof hybrid approximation, corrected many-body dispersion effects. latter, more advanced method treating dispersion, known to produce binding energies nearly twice as small those obtained with pairwise correction schemes, used an earlier ILP parametrization. yields good agreement reference ∼1 and ∼0.5 meV/atom sliding energies, respectively. For completeness, we present a complementary parameter set homogeneous graphitic systems. Together our previously suggested heterogeneous graphene/h-BN junction, this provides powerful tool consistent simulation structural, mechanical, tribological, heat transp...
