Abstract
We investigate one-dimensional (1-D) nanostructures formed by deposition
of potassium on InAs(110) surface and of pentacene on the vicinal
Cu(119) surface. Scanning tunneling microscopy (STM) reveals the
morphology and the long-range ordering of the nanostructures.
Voltage-dependent STM images are used to investigate the electronic
structure in the real space. The potassium chains give rise to a
delocalized continuum of charge density, suggesting their 1-D electronic
nature. 1-D pentacene rows, growing beyond the completion of the first
layer, do not show a similar behavior. The formation of the 1-D
electronic structures is discussed in term of the substrate-adsorbate
interaction. (C) 2004 Elsevier B.V. All rights reserved.
