"State-of-the-art nanoelectromechanical systems have been demonstrated in recent years using carbon nanotube (CNT) based device, where the vibration of CNTs is turned by tension induced through external electrical fields. However, the vibration properties of CNTs under axial tension have not been quantitatively determined in experiments," scientists in Beijing, People's Republic of China report.
"Here, a novel in situ method for precise and simultaneous measurement of the resonance frequency the axial tension applied to individual CNTs and the tube geometry is demonstrated. A gradual beam-to-string transition from multi-walled CNTs to single-walled CNTs is ...
