We conclude this section for electronic and spintronic properties by mentioning that 2D-COF-Mn-05 presents a peculiar band structure, with spin-down bands that resemble a double Dirac cone near the Fermi level (see Figure ). A similar phenomenon has been theoretically predicted in S-Graphene. With Mn-05 intercalation, we potentially find a new topological material; however, analyzing this phenomenon requires the introduction of relativistic effects (namely, spin-orbit coupling) to our calculations, which we have not considered here. Thus, we leave this for future work.
