As such, we encourage other researchers to include van der Waals corrections in any future studies involving the calculation of exfoliation energies. We note that there is a discrepancy between the values of standard deviation of charge effective mass for the p-and n-type datasets, observable in Figure . Whereas the smallest standard deviation for the n-type results is 5.14, the smallest value for the ptype results is 31.1. This indicates that sampling the conduction band can give a broader range of values across the same set of materials than does the valence band and is perhaps therefore a more suitable resource for use in future screening. Once again, this observation is somewhat intuitive and relatable to fundamental materials physics in that higher energy bands in general are less likely to be strongly bonding when compared to lower energy bands due to the shielding effects of the deeper, core states of the material. With less strong bonding, the bands are likely to be relatively flatter and hence give rise to a greater standard deviation for the charge effective mass tensor.
