Wires having a width of one or two atoms are the smallest possible physical objects that may
exhibit one-dimensional properties. In order to be experimentally accessible at finite …

As the ultimate one-dimensional (1D) systems, ordered assemblies of monatomic chains,
bound stably on the surface of thin atomic layers with good transferability, attachability, and …

Low-dimensional self-organized surface structures, induced by (sub) monolayer metal
adsorbates on semiconductor surfaces may give rise not only to a variety of emergent …

The plasmonic signals of quasi-1D electron systems are a clear and direct measure of their
metallic behavior. Due to the finite size of such systems in reality, plasmonic signals from a …

Si (111)-(5× 2)-Au represents a prototype system for an adsorbate-induced spontaneous
symmetry break by formation of quasi-one-dimensional atomic chains that are metallic …

Ordered submonolayers of adsorbate atoms on semiconductor surfaces constitute a
playground for electronic correlation effects, which are tightly connected to the local atomic …

Scanning tunneling microscopy (STM) and angle-resolved photoemission spectroscopy
(ARPES) observations combined with the density functional theory (DFT) calculations were …

The strong sensitivity of plasmonic excitations on nanostructures to their environment is
studied, going to the ultimate limit of single atomic chains. As a first step, we investigated …

We investigate the effects of native Si adatoms on structural and electronic properties of the
Si (111) 5× 2-Au surface, a representative one-dimensional metal-chain system, by means …

Abstract Changes in the structural and electronic properties of the quasi-one-dimensional
metal-chain Au/Si (111) 5× 2 reconstruction induced by Bi adsorption were investigated …
