Abstract
To investigate the mechanical properties of quasi-2D layered networks composed of chiral multi-walled carbon nanotubes and their bundles, a methodology has been developed for constructing atomistic supercell models based on chiral nanotubes of the $(m,2m)$ type. These networks feature X-shaped van der Waals junctions between nanotubes, with varying periodicity steps along two mutually perpendicular directions. The methodology, formulated as a sequential algorithm of mathematical operations, is universal and can be applied to any configuration of multi-walled carbon nanotubes and their bundles, regardless of the number of constituent nanotubes. The developed approach also enables precise control over the network periodicity — i.e., the size of the window formed by the interconnected tubes. Validation of the methodology was performed using examples of individual double-walled carbon nanotubes and bundles containing both two and three nanotubes.
