Arroyo-Gascón et al., One-Dimensional Moiré Superlattices and Flat Bands in Collapsed Chiral Carbon Nanotubes, Nano Lett. 2020, 20, 10, 7588–75931530-698410.1021/acs.nanolett.0c03091https://hdl.handle.net/20.500.14352/119829We demonstrate that one-dimensional moiré patterns, analogous to those found in twisted bilayer graphene, can arise in collapsed chiral carbon nanotubes. Resorting to a combination of approaches, namely, molecular dynamics to obtain the relaxed geometries and tight-binding calculations validated against ab initio modeling, we find that magic angle physics occur in collapsed carbon nanotubes. Velocity reduction, flat bands, and localization in AA regions with diminishing moiré angle are revealed, showing a magic angle close to 1°. From the spatial extension of the AA regions and the width of the flat bands, we estimate that many-body interactions in these systems are stronger than in twisted bilayer graphene. Chiral collapsed carbon nanotubes stand out as promising candidates to explore many-body effects and superconductivity in low dimensions, emerging as the one-dimensional analogues of twisted bilayer graphene.engjournal article1530-6992https://doi.org/10.1021/acs.nanolett.0c03091https://pubs.acs.org/doi/10.1021/acs.nanolett.0c03091https://arxiv.org/abs/2007.15558open access538.9Moiré superlatticesChiral carbon nanotubesFlat bandsTwisted bilayer grapheneFísica de materialesFísica del estado sólido2211 Física del Estado Sólido
