Structure and superconductivity in the binary Re1-xMox alloys

Joël Mesot

The binary Re1-xMox alloys, known to cover the full range of solid solutions, were successfully synthesized and their crystal structures and physical properties investigated via powder x-ray diffraction, electrical resistivity, magnetic susceptibility, and ...

Robustness of Yu-Shiba-Rusinov resonances in the presence of a complex superconducting order parameter

Klaus Kern, Markus Etzkorn, Jacob Senkpiel

Robust quantum systems rely on having a protective environment with minimized relaxation channels. Super-conducting gaps play an important role in the design of such environments. The interaction of localized single spins with a conventional superconductor ...

Yttrium Tantalum Oxynitride Multiphases as Photoanodes for Water Oxidation

Nicola Marzari, Ivano Eligio Castelli

The perovskite yttrium tantalum oxynitride is theoretically proposed as a promising semiconductor for solar water splitting because of the predicted band gap and energy positions of band edges. In experiments, however, we show here that depending on the pr ...

Nodeless superconductivity in the noncentrosymmetric Mo3Rh2N superconductor: A mu SR study

Joël Mesot

The noncentrosymmetric superconductor Mo3Rh2N, with T-c = 4.6 K, adopts a beta-Mn-type structure (space group P4(1)32), similar to that of Mo3Al2C. Its bulk superconductivity was characterized by magnetization and heat-capacity measurements, while its micr ...

Scanning Tunneling Spectroscopy with Superconducting Junctions : From Single Channel Transport to Local Pair Breaking Potentials

Jacob Senkpiel

This thesis contains two major topics, the restriction of tunneling to only a few channels in the scanning tunneling microscope (STM) and the interaction of local magnetic impurities with superconductivity. At a temperature of 15mK, the quantum back-action ...

Scaling of the superconducting gap with orbital character in FeSe

Timur Kim

We use high-resolution angle-resolved photoemission spectroscopy to map the three-dimensional momentum dependence of the superconducting gap in FeSe. We find that on both the hole and electron Fermi surfaces, the magnitude of the gap follows the distributi ...

Time-Reversal Symmetry Breaking in Re-Based Superconductors

Joël Mesot, Johan Juul Chang

To trace the origin of time-reversal symmetry breaking (TRSB) in Re-based superconductors, we performed comparative muon-spin rotation and relaxation (mu SR) studies of superconducting noncentrosymmetric Re0.82Nb0.18 (T-c = 8.8 K) and centrosymmetric Re (T ...

Dynamics of correlation-frozen antinodal quasiparticles in superconducting cuprates

Alberto Crepaldi

Many puzzling properties of high-critical temperature (T-c) superconducting (HTSC) copper oxides have deep roots in the nature of the antinodal quasiparticles, the elementary excitations with wave vector parallel to the Cu-O bonds. These electronic states ...

Spectroscopic Studies of the Electronic Structure in Layered Cuprates and Ruthenates

Claudia Giuseppina Fatuzzo

In materials where electrons interact strongly, a number of exotic and exciting phenomena arise. The mechanisms at the base of many of these phenomena remain debated, as strongly correlated electron physics represents one of the biggest challenges for mode ...

Clean, cleaved surfaces of the photovoltaic perovskite

László Forró, Henrik Moodysson Rønnow, Jeremy Luterbacher, Jan Hugo Dil, Endre Horvath, Stefan Peter Muff, Andrew Patton Weber, Luka Ciric, Benjamin Pierre Le Monnier, Bálint Náfrádi

The surface of a material is not only a window into its bulk physical properties, but also hosts unique phenomena important for understanding the properties of a solid as a whole. Surface sensitive techniques, like ARPES (Angle-resolved photoemission spect ...
