Abstract

Atomically resolved room temperature scanning tunneling microscopy images of carbon nanotubes were obtained, and actual values of the nanotube dimensions were estimated from a line profile fitting analysis. It was found that the cross sectional deformation induced by the van der Waals forces between the CNTs and the substrate is much smaller in the double-walled carbon nanotubes than in the single-walled nanotubes.
