Universality of moiré physics in collapsed chiral carbon nanotubes

Carbon Kagome nanotubes—quasi-one-dimensional nanostructures with flat bands

“…37,[60][61][62][63][64][65][66][67] On the other hand, although several 1D allotropes of carbon are well known, [68][69][70][71][72][73][74][75][76][77][78][79] none of these systems are usually associated with at band physics. As far as we can tell, there have been only a few earlier attempts at producing and investigating at bands in realistic 1D nanomaterials of carbon: partially at bands in zigzag graphene nanoribbons, 80 spin polarized at bands in hydrogenated carbon nanotubes, 81 and moiré type at bands in chiral carbon nanotubes with collapsed structures 82,83 or incommensurate double wall geometries. 84 Our contribution aims to address this particular gap in the literature by studying a family of realistic 1D carbon nanostructures that naturally feature at bands throughout their Brillouin zone.…”
