Carbon nanotubes (CNTs) can be synthesized from amorphous carbon thin films by electron irradiation in the transmission electron microscope (TEM). We propose that irradiation effects impart a tensile stress and introduce defects to a CNT thus formed and show that the CNTs can be made to fracture by a brittle or ductile mechanism. We also report a healing of the carbon film that is observed after some critical amount of irradiation.
