Figure 2From: Dirac cone in α-graphdiyne: a first-principles studyElectronic properties of α -graphdiyne. (a) Band structure and (b) DOS. (c) First Brillouin zone with the letters designating high-symmetry points. (d) 2D Dirac cone representing the valence and conduction bands in the vicinity of the K and K′ points. EF is the Fermi energy.Back to article page
