Ballistic surface channels in fully in situ defined BiTe Josephson junctions with aluminum contacts
Daniel Rosenbach, Abdur R. Jalil, Tobias W. Schmitt +5
In this letter we report on the electrical transport properties of BiTe in a Josephson junction geometry using superconducting Al electrodes with a Ti interdiffusion barrie…
Spin coherence of near-surface ionised Te donors in silicon
Mantas Šimėnas, James O'Sullivan, Oscar W. Kennedy +8
Impurity spins in crystal matrices are promising components in quantum technologies, particularly if they can maintain their spin properties when close to surfaces and material int…
Integration of topological insulator Josephson junctions in superconducting qubit circuits
Tobias W. Schmitt, Malcolm R. Connolly, Michael Schleenvoigt +16
The integration of semiconductor Josephson junctions (JJs) in superconducting quantum circuits provides a versatile platform for hybrid qubits and offers a powerful way to probe ex…
Phase-coherent loops in selectively-grown topological insulator nanoribbons
Jonas Kölzer, Daniel Rosenbach, Christian Weyrich +9
Universal conductance fluctuations and the weak antilocalization effect are defect structure specific fingerprints in the magnetoconductance that are caused by electron interferenc…
Adsorption and Intermolecular Interaction of Cobalt Phthalocyanine on CoO(111) Ultrathin Films: An STM and DFT Study
Tobias Schmitt, Pascal Ferstl, Lutz Hammer +2
We investigate the adsorption of cobalt phthalocyanine (CoPc) molecules on a thin layer of cobalt oxide grown on Ir(100). To that end we compare the results of low-temperature scan…
Magnetotransport signatures of three-dimensional topological insulator nanostructures
Kristof Moors, Peter Schüffelgen, Daniel Rosenbach +3
We study the magnetotransport properties of patterned 3D topological insulator nanostructures with several leads, such as kinks or Y-junctions, near the Dirac point with analytical…
