Fig. 5: Boron nitride (BN) derivatives of materials based on azulenoid kekulene.
From: Prediction of highly stable 2D carbon allotropes based on azulenoid kekulene
Structures of (a) BN-AKC-[3,3], (b) BN-PAC-[3,3], and (c) BN-PG-[3,3] materials. Pentagons and heptagons are shown with red and blue colors, respectively. The coronene units inside the AK unit are shown with gray color, whereas the graphene matrix is colored white. d–f The corresponding HSE band structure diagrams. The boron and nitrogen atoms are shown in green and purple circles, respectively. In the band structure diagrams, the blue and orange lines show the valence and conduction bands, respectively.
