Narrow-Diameter Tubular One-Dimensional van der Waals Heterostructures.

ABSTRACT: The inherent flexibility of individual layers in 2D materials enables them to be rolled up into tubular structures, thereby combining the properties of 1D and 2D materials and further expanding their range of applications. Even greater opportunities arise when two or more layers of different materials are combined, forming 1D tubular van der Waals heterostructures. Herein, the synthesis, structural characterization, and electronic properties of narrow 1D van der Waals heterostructures with internal diameters as low as ≈1 nm are reported. These are achieved by template-assisted growth of highly crystalline, single-layer lutetium halide (LuX₃, X = Cl, Br, I) nanotubes confined within the cavities of single-walled carbon nanotubes.
