We investigate the electronic structure of silver nanowires at 1 monolayer (ML) Ag coverage on a vicinal Si(557) substrate by angle-resolved photoemission spectroscopy. Fermi surface mapping reveals two-dimensional (2D) Ag-induced electron pockets, w

We investigated the metallicity of Ag- $\sqrt{3}$ ordered atomic wires close to one monolayer (ML) coverage, which are formed on Si(557) via self assembly. For this purpose we combined high resolution electron energy loss spectroscopy with tunneling

We generated arrays of silver wires with a height of 1 atom and an average width of 11 atoms on the Si(557) surface via self-assembly with local $\sqrt{3}\times \sqrt{3}$ order, and investigated the 1D plasmon formation in them using a combination of

Exploring ways for self-organized structuring of insulating thin films, we investigated the possibility to produce replicas of step trains, given by a vicinal Si(0 0 1)-4°[1 1 0] surface, in layers of crystalline and perfectly lattice-matched Ba 0.7

Kinetic growth modes of Si in the submonolayer regime on vicinal Ge(1 0 0) surfaces miscut by 2.7° and 5.4° towards the [0 1 1] direction were investigated using low energy electron diffraction (LEED) and photoelectron spectroscopy (XPS, UPS). At a

Low energy electron diffraction (LEED) measurements have been carried out on the clean and Te covered Pd(1 0 2) surface. This is the surface into which the Pd(1 0 0) surface is reconstructed by a concentration of more than 0.5 ML of Te. The Pd(1 0 2)

The local geometries of Li adsorbed on the furrowed (211) surface of Mo have been investigated by a LEED-IV analysis using an energy of 30–180 eV. Adsorbate-induced lateral interactions mediated mainly through the substrate turn out to be mainly re

The adsorption geometry and the adsorbate induced relaxations of p (2 × 2 ) ordered oxygen on Ni (111) have been reinvestigated by a dynamical LEED analysis in the energy range between 30 and 387 eV. 14 non-equivalent beams have been recorded with a
