Título: | Subnanometer Motion of Cargoes Driven by Thermal Gradients Along Carbon Nanotubes |
Autor: | Barreiro, Amelia CSIC; Rurali, Riccardo CSIC ORCID ; Hernández, Eduardo R. CSIC ORCID; Moser, Joel CSIC ORCID; Pichler, Thomas; Forró, László; Bachtold, Adrian CSIC ORCID | Fecha de publicación: | 10-abr-2008 | Editor: | American Association for the Advancement of Science | Citación: | Science 320(5877): 775-778 (2008) | Resumen: | An important issue in nanoelectromechanical systems is developing small electrically driven motors. We report on an artificial nanofabricated motor in which one short carbon nanotube moves relative to another coaxial nanotube. A cargo is attached to an ablated outer wall of a multiwalled carbon nanotube that can rotate and/or translate along the inner nanotube. The motion is actuated by imposing a thermal gradient along the nanotube, which allows for subnanometer displacements, as opposed to an electromigration or random walk effect. | Descripción: | 4 pages, 4 figures.-- Printed version published May 9, 2008.
