Narrow‐Diameter Tubular One‐Dimensional van der Waals Heterostructures
Small, Volume 21, Issue 51, December 23, 2025.Narrow 1D van der Waals heterostructures are formed by template‐assisted growth of single‐layer lutetium halide nanotubes, down to ≈1 nm diameter, inside single‐walled carbon nanotubes. The role of the halide size on nanotube formation is elucidated by means of aberration‐corrected electron microscopy and image simulations, while the electronic ...
