Abstract

A simple method for spatially selective removal of single-walled carbon nanotubes is demonstrated. This method is based on low-acceleration-voltage electron irradiation damage and consists of local electron irradiation of nanotubes and annealing in air. The irradiation damage seems to follow excitation of valence electrons.
