Abstract

Helical oxide nanotubes prepared by atomic layer deposition (ALD) replicate the helical morphology of the carbon-nanocoil 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.
