Two-dimensional flat-bands in Moire-diamonds
Yalan Wei, Shifang Li, Yuke Song +1
The discovery of flat-bands in magic-angle twisted bilayer graphene has underscored the potential of moire engineering for correlated states, but such phases are notoriously diffic…

Theoretical prediction of a low-energy Stone-Wales graphene with intrinsic type-III Dirac-cone
Zhenghao Gong, XiZhi Shi, Jin Li +6
Based on first-principles method we predict a new low-energy Stone-Wales graphene SW40, which has an orthorhombic lattice with Pbam symmetry and 40 carbon atoms in its crystalline…
