Scientists can already transform materials like carbon nanotubes and transition metal chalcogenides (TMCs), mixtures of transition metals and group 16 elements which can self-assemble into atomic-scale nanowires. These have three-atom diameters (with chalcogen atoms occupying three corners of a triangular-like frame and metal atoms in the middle of each side) and van der Waals surfaces, and have been reported to possess a one-dimensional metallic nature.
Although TMCs were discovered 40 years ago, creating them at scale and at useful lengths is still a challenge and mass production of nanowires has so far remained out of reach.
Now, a Tokyo Metropolitan University team has developed a method for creating long wires of transition metal telluride nanowires at unprecedented scales.
Using CVN, they can assemble these nanowires into different configurations depending on the substrate they use as a template. Adjusting the structure of the substrate allowed the researchers to create centimetre-sized wafers covered in arrangements including atomically-thin sheet-like monolayers, bilayers, and random networks of bundles of wires, all with different applications.
The structure of the nanowires themselves were highly crystalline and ordered, and their properties (including excellent conductivity and one-dimensional-like behaviour) matched those predicted by theory.
