An InAsSb surface quantum well with in-situ deposited Nb as a platform for semiconductor-superconductor hybrid devices
Sjoerd Telkamp, Zijin Lei, Tommaso Antonelli +7
We present a novel semiconductor-superconductor hybrid material based on a molecular beam epitaxially grown InAsSb surface quantum well with an in-situ deposited Nb top layer. Rela…
High-temperature growth of ultra thin NbTiN films on lithium niobate for integrated single photon detection
Sjoerd Telkamp, Odiel Hooybergs, Myriam Rihani +9
Lithium niobate-on-insulator (LNOI) is an emerging photonic platform with high potential for scalable quantum information processing due to its strong second-order nonlinearity. Ho…
Exploring the energy spectrum of a four-terminal Josephson junction: Towards topological Andreev band structures
Tommaso Antonelli, Marco Coraiola, David Christian Ohnmacht +10
Hybrid multiterminal Josephson junctions (JJs) are expected to harbor a novel class of Andreev bound states (ABSs), including topologically nontrivial states in four-terminal devic…
Improving Electrical Contact Quality and Extraordinary Magnetoresistance in High Mobility III-V Semiconductors
Thierry Désiré Pomar, Tristan Steegemans, Sreejith Kumar +8
Magnetometers based on the extraordinary magnetoresistance (EMR) effect are promising for applications which demand high sensitivity combined with room temperature operation but th…
Spin polarization of Quantum Hall states for filling factors 1 < v < 2 measured with microcavity polaritons
Odysseas Williams, Stefan Faelt, Filip Krizek +1
Spin polarization measurements were performed in three 2D Electron Gases in GaAs with densities n = 9.1, 7.2 and 6.5 x10^10 cm-2, in the quantum Hall regime. Full spin polarization…
