Helical oxide nanotubes prepared by atomic layer deposition (ALD) replicate the helical morphology of the carbonnanocoil templates. ALD is superior to other coating technologies for the high‐curvature surfaces of the nanostructures in terms of conformality and thickness control. The helical nanotubes have much better elasticity than straight nanotubes.
