For example, PBE+TS estimates for the total energies AB>AA, in agreement with previous DFTB results, while the other five PBE+vdW models and SCAN+rVV10 predict that AA>AB, consistent with a prior PBE+D3(BJ) study. In addition, the quantitative disagreement between SCAN+rVV10, PBE+MBD, PBE+D2, PBE+D3 and PBE+D3(BJ) is large. The calculated energetic differences between AA and AB stacking range from -0.22 eV/layer to 0.08 eV/layer.
