Abstract
We have performed STM measurements on nitric acid treated, functionalised multiwalled carbon nanotubes. Atomic resolution STM images around defects created by the acid treatment show circular √3 × √3 R30° type superstructures. We have used a simple scattering model to reproduce the experimentally observed STM images and show that such superstructures can be obtained by considering only the contribution of β site carbon atoms, known to dominate the STM image of graphite and multiwalled carbon nanotubes (MWCNTs).
