| Popis: | We report the details of an electron-beam-induced crystallization process of amorphous carbon. A high-resolution transmission electron microscope having a homemade nanomanipulator was used to observe defect repairing and the plastic deformation of a carbon nanotube caused by Joule heating. Electron irradiation at 200keV combined with 10@mA Joule heating at 2V biasing voltage induced the crystallization of carbon nanocapsules from an amorphous carbon fibril. Further, a current exceeding 20@mA caused defect repairing prior to plastic deformation in a multiwalled carbon nanotube. The outermost layer of the buckled multiwalled nanotube was repaired, but the buckled innermost layer retained its sharp angles as a result of plastic deformation. |
