CSIC ORCID ; Biró, László Péter | Fecha de publicación: | 2003 | Editor: | Elsevier | Citación: | Materials Science and Engineering: C 23(4): 561-564 (2003) | Resumen: | The scanning tunneling microscopy (STM) observation of arc-grown Y-branched carbon nanotubes and sharp nanotube bends (nano-knees) is reported. A drilled out graphite rod filled with a nickel/yttrium particle mixture was used as the anode in an arc chamber under He atmosphere of 660-mbar pressure. Straight multi-wall nanotubes, Y-branches and nano-knees were found in a sample taken from the cathodic deposit. The asymmetrical Y-branches and complex nano-knees found in this experiment may be related to the additional use of metals or/and to induced changes of the temperature distribution on the cathode side. It is suggested that complex nano-knees could be new examples for carbon quantum dots. | Versión del editor: | https://doi.org/10.1016/S0928-4931(03)00032-8 | URI: | http://hdl.handle.net/10261/255204 | DOI: | 10.1016/S0928-4931(03)00032-8 | ISSN: | 0928-4931 |
