Thickness-directed oxide-templated conversion of sputtered tungsten films into WS ₂ nanotubes

This is the authors' abstract. We don't add key points for this paper.

W film thickness alone selects the topology of oxide-templated WS 2 : hollow at 5 nm, a WO x remnant at 10 nm, and a retained core at 100 nm, turning a growth by-product into a design parameter.
