Article Synopsis
  • Classic graphene has remarkable properties linked to its Dirac cone structures, leading to predictions of various Dirac cone materials.
  • A new carbon allotrope called azugraphene was discovered using a first-principle search algorithm, featuring a complex structure with 38 atoms that include three 5-7 ring fragments from azulene and a hexagon.
  • Azugraphene exhibits six Dirac cones and is stable enough to be synthesized, with its bilayer form showing a band gap of 2.5 meV, making it promising for applications in physics, chemistry, and nanoelectronics.
