Electrode/electrolyte interfaces play a crucial role in many electrochemical energy
conversion and storage technologies. Hence, a deep understanding of the interfacial …

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 …

We present a state-of-the-art study of the optical properties of free-standing silicene and of
single-layer Si one-and two-dimensional (1D and 2D) nanostructures supported on Ag (110) …

Anisotropic media induce changes in the polarization state of transmitted and reflected light.
Here we combine this effect with the refractive index sensitivity typical of plasmonic …

We identify the atomic structure of the Au/Si (111)-(5× 2) surface by using density functional
theory calculations. With seven Au atoms per unit cell, our model forms a bona fide (5× 2) …

The geometry and electronic structure of self-assembled atomic scale Au wires on Si (775)
are investigated within density functional theory. The calculated surface diagram indicates …

We study and analyze the growth of submonolayers of Au on Si (111) by a complementary
set of surface techniques. Specifically, we focus on the 5× 2 and the α 3× 3 structures. We …

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 …

Atomic scale nanowires attract enormous interest in a wide range of fields. On the one hand,
due to their quasi-one-dimensional nature, they can act as an experimental testbed for …

The atomic structure of the Si (111)-(5× 2)-Au surface, a periodic gold chain on the silicon
surface, has been a long-debated issue in surface science. The recent three candidates, the …
