Title: Electronic Effects in Length Distribution of Atom Chains
Published: April 17, 2006
Abstract: Gold deposited on Si(553) leads to self assembly of atomic chains, which are broken into finite segments by atomic defects. Scanning tunneling microscopy is used to investigate the distribution of chain lengths and the correlation between defects separating the chains. The length distribution reveals incommensurate oscillations that are linked to the electronic scattering vectors at the Fermi surface of the surface states. The pair-wise correlation function between defects shows longer range correlations than a prediction from the chain length distribution, which assumes nearest neighbor interactions alone. These correlations indicate a coupling between chains.
