Reconstruction-induced trefoil knot Fermi contour of Au(111)
Maciej Dendzik, Marco Bianchi, Matteo Michiardi +2
Using angle-resolved photoemission spectroscopy (ARPES), we study the effect of the so-called herringbone reconstruction of Au(111) on the dispersion of the free electron-like surf…
Absence of superconductivity in ultra-thin layers of FeSe synthesized on a topological insulator
Andreas Eich, Nils Rollfing, Fabian Arnold +10
The structural and electronic properties of FeSe ultra-thin layers on BiSe have been investigated with a combination of scanning tunneling microscopy and spectroscopy a…
Non-magnetic ground state of Ni adatoms on Te-terminated bismuth chalcogenide topological insulators
M. Vondracek, J. Honolka, L. Cornils +20
We report on the quenching of single Ni adatom moments on Te-terminated Bi2Te2Se and Bi2Te3 topological insulator surfaces. The effect becomes manifested as a missing X-ray magneti…
Band gap engineering by Bi intercalation of graphene on Ir(111)
Jonas Warmuth, Albert Bruix, Matteo Michiardi +7
We report on the structural and electronic properties of a single bismuth layer intercalated underneath a graphene layer grown on an Ir(111) single crystal. Scanning tunneling micr…
Topological insulator homojunctions including magnetic layers: the example of n-p type (-QLs BiSe/Mn-BiSe) heterostructures
M. Valiska, J. Warmuth, M. Michiardi +9
Homojunctions between BiSe and its Mn-doped phase are investigated as a sample geometry to study the influence of spin degrees of freedom on topological insulator propertie…
