The gold ticket to achiral WS2 nanotubes

Multiwalled WS2 and WSe2 nanotubes with predominantly a single chiral angle are produced in a chemical vapour deposition reactor using gold nanoparticles as a catalyst. This strategy paves the way for the growth of transition metal dichalcogenide nanotubes with controllable structures for further exploring their physical properties and potential applications.
