Thermoelectric power of overdoped Tl2201 crystals: charge density waves and resistivities
We report measurements of the in-plane thermoelectric power (TEP) for an overdoped (OD) crystal of the single layer cuprate superconductor Tl2Ba2CuO6+x (Tl2201) at several hole concentrations (p), from 300 or 400 K to below the superconducting transition t ...
Bristol2024Scaling of the superconducting gap with orbital character in FeSe
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 ...
2018High-energy electronic interaction in the 3d band of high-temperature iron-based superconductors
Maryna Viazovska, Helmuth Berger
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 ...
Amer Physical Soc2017Spectroscopic Studies of the Electronic Structure in Layered Cuprates and Ruthenates
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 ...
EPFL2017Spin-resolved band structure of a densely packed Pb monolayer on Si(111)
Jan Hugo Dil, Stefan Peter Muff, Mauro Fanciulli
Monolayer structures of Pb on Si(111) attracted recently considerable interest as superconductivity was found in these truly two-dimensional (2D) structures. In this study, we analyzed the electronic surface band structure of the so-called striped incommen ...
Amer Physical Soc2017High-temperature superconductivity from fine-tuning of Fermi-surface singularities in iron oxypnictides
In the family of the iron-based superconductors, the REFeAsO-type compounds (with RE being a rare-earth metal) exhibit the highest bulk superconducting transition temperatures (T-c) up to 55 K and thus hold the key to the elusive pairing mechanism. Recentl ...
