Observation of tunable single-atom Yu-Shiba-Rusinov states
Artem Odobesko, D. Di Sante, A. Kowalski +5
The coupling of a spin to an underlying substrate is the basis for a plethora of phenomena. In the case of a metallic substrate, Kondo screening of the adatom magnetic moment can o…
On the preparation and electronic properties of clean superconducting Nb(110) surfaces
Artem B. Odobesko, Soumyajyoti Haldar, Stefan Wilfert +7
We have studied cleaning procedures of Nb(110) by verifying the surface quality with low-energy electron diffraction, Auger electron spectroscopy, and scanning tunneling microscopy…
Breaking crystalline symmetry of epitaxial SnTe films by strain
Steffen Schreyeck, Karl Brunner, Laurens W. Molenkamp +7
SnTe belongs to the recently discovered class of topological crystalline insulators. Here we study the formation of line defects which break crystalline symmetry by strain in thin…
Scanning tunneling spectroscopy investigations of superconducting-doped topological insulators: Experimental pitfalls and results
Stefan Wilfert, Paolo Sessi, Zhiwei Wang +8
Recently the doping of topological insulators has attracted significant interest as a potential route towards topological superconductivity. Because many experimental techniques la…
Robust spin-polarized midgap states at step edges of topological crystalline insulators
Paolo Sessi, Domenico Di Sante, Andrzej Szczerbakow +11
Topological crystalline insulators are materials in which the crystalline symmetry leads to topologically protected surface states with a chiral spin texture, rendering them potent…
Mapping the effect of defect-induced strain disorder on the Dirac states of topological insulators
Oliver Storz, Alberto Cortijo, Stefan Wilfert +6
We provide a detailed microscopic characterization of the influence of defects-induced disorder onto the Dirac spectrum of three dimensional topological insulators. By spatially re…
