Lett. 90, 186102 (2003) Localized Molecular Constraint on Electron Delocalization in a Metallic Chain N. Nilius, T. M. Wallis, and W. Ho Department of Physics and Astronomy and Department of Chemistry, University of California, Irvine, California 92697-4575, USA (Received 27 January 2003; published 9 May 2003) An artificial quantum structure consisting of a single CO molecule adsorbed on a Au chain was assembled by manipulating single Au atoms on NiAl(110) at 12 K with a scanning tunneling microscope (STM). The CO disrupts the delocalization of electron density waves in the chain, as it suppresses the coupling between neighboring chain atoms. The possibility to specify the CO position on the chain allows controlled modification of the electronic properties in a quantum system. Inelastic electron tunneling spectroscopy with the STM provides vibrational characterization of the adsorbed CO. ©2003 The American Physical Society URL: http://link.aps.org/abstract/PRL/v90/e186102 doi:10.1103/PhysRevLett.90.186102 PACS: 68.37.Ef, 68.43.Fg, 73.21.Fg Posted by nano @ 2003-05-11 01:42 Comments Add Comment Last update Cobalt breaks magnetism record Giant Magnetic Anisotropy of Single Cobalt Atoms and Nanoparticles nanoscience & technology conference Scientists make waves with terahertz device 【图文】飞秒激光切削加工技术将进入实用阶段 New PRL paper by W.
