High-energy electronic interaction in the 3d band of high-temperature iron-based superconductors

One of the most unique and robust experimental facts about iron-based superconductors is the renormalization of the electronic band dispersion by factor of 3 and more near the Fermi level. Obviously related to the electron pairing, this prominent deviation ...

4 f occupancy and magnetism of rare-earth atoms adsorbed on metal substrates

Harald Brune, Stefano Rusponi, Christian Wäckerlin, Jan Gui-Hyon Dreiser, Pietro Gambardella, Fabio Donati, Aparajita Singha, Romana Baltic, Sebastian Stepanow

We report x-ray absorption spectroscopy and x-ray magnetic circular dichroism measurements as well as multiplet calculations for Dy, Ho, Er, and Tm atoms adsorbed on Pt(111), Cu(111), Ag(100), and Ag(111). In the gas phase, all four elements are divalent a ...

Strong paramagnon scattering in single atom Pd contacts

Klaus Kern, Markus Ternes, Uta Schlickum, Peter Wahl, Ivan Pentegov, Verena Katharina Schendel

Among all transition metals, palladium (Pd) has the highest density of states at the Fermi energy at low temperatures yet does not fulfill the Stoner criterion for ferromagnetism. However, close proximity to magnetism renders it a nearly ferromagnetic meta ...

Variation of the Fermi level and the Electrostatic Force of a Metallic Nanoparticle upon Colliding with an Electrode

Hubert Girault, Pekka Eero Peljo

When a metallic nanoparticle (NP) comes in close contact with an electrode, its Fermi level equilibrates with that of the electrode if their separation is less than the cut-off distance for electron tunnelling. In the absence of chemical reactions in solut ...

Study of Si doped VO2 thin films for solar thermal applications

Andreas Schueler, Anna Krammer, Olivia Valérie Charlotte Bouvard

A new generation of smart solar thermal collectors is based on thermochromic thin film technology. Thermochromic absorber coatings change their optical properties with temperature, particularly in the infrared range. In order to prevent overheating, the co ...

Monovalent Cation Doping of CH3NH3PbI3 for Efficient Perovskite Solar Cells

Mohammad Ibrahim Dar, Mojtaba Abdi Jalebi

Here, we demonstrate the incorporation of monovalent cation additives into CH3NH3PbI3 perovskite in order to adjust the optical, excitonic, and electrical properties. The possibility of doping was investigated by adding monovalent cation halides with simil ...
