Temperature dependence of surface superconductivity in t-PtBi
Julia Besproswanny, Sebastian Schimmel, Yanina Fasano +5
The Weyl semimetal trigonal PtBi has recently been identified as a promising candidate material for intrinsic topological surface superconductivity emerging from the Fermi arc…
Bulk and surface electron scattering in disordered BiTe probed by quasiparticle interference
Vladislav Nagorkin, Sebastian Schimmel, Paul Gebauer +5
We investigated the electronic properties of the topological insulator BiTe by scanning tunneling microscopy and spectroscopy at low temperature. We obtained high-resol…
Fermi arcs dominating the electronic surface properties of trigonal PtBi
Sven Hoffmann, Sebastian Schimmel, Riccardo Vocaturo +10
Materials combining topologically non-trivial behavior and superconductivity offer a potential route for quantum computation. However, the set of available materials intrinsically…
Surface superconductivity in the topological Weyl semimetal t-PtBi
Sebastian Schimmel, Yanina Fasano, Sven Hoffmann +10
The advancement of quantum computation is eager on generating fault tolerant qubits, and topological superconductivity is a very promising concept for reaching this goal. Early exp…
Unusual heat transport of the Kitaev material NaCoTeO: putative quantum spin liquid and low-energy spin excitations
Xiaochen Hong, Matthias Gillig, Richard Hentrich +10
We studied the field dependent thermal conductivity () of NaCoTeO, a compound considered as the manifestation of the Kitaev model based on the high-spin Co$^{2…
An ultra-high vacuum scanning tunneling microscope operating at sub-Kelvin temperatures and high magnetic fields for spin-resolved measurements
C. Salazar, D. Baumann, T. Hänke +7
We present the construction and performance of an ultra-low temperature scanning tunneling microscope (STM), working in ultra-high vacuum conditions (UHV) and in high magnetic fiel…
