Figure 3.
Relative frequency and experimental band gap as a function of the ratio between theoretical and experimental band gaps for the different xc functionals: (a) comparison of HLE16 with and without spin–orbit coupling effect; (b) LDA with and without spin–orbit coupling; (c) comparison of GGA functionals; (d) comparison of mGGA functionals; (e) comparison of screened hybrid functionals; (f) comparison of PBE0 with PBE0mix. For representation purposes the x-axis of these plots was truncated at 1.6.
