Development of a Nb-based semiconductor-superconductor hybrid platform
Sjoerd Telkamp, Tommaso Antonelli, Clemens Todt +12
Semiconductor-superconductor hybrid materials are used as a platform to realise Andreev bound states, which hold great promise for quantum applications. These states require transp…
The effect of niobium thin film structure on losses in superconducting circuits
Maxwell Drimmer, Sjoerd Telkamp, Felix L. Fischer +7
The performance of superconducting microwave circuits is strongly influenced by the material properties of the superconducting film and substrate. While progress has been made in u…
Development of Nb-GaAs based superconductor semiconductor hybrid platform by combining in-situ dc magnetron sputtering and molecular beam epitaxy
Clemens Todt, Sjoerd Telkamp, Filip Krizek +10
We present Nb thin films deposited in-situ on GaAs by combining molecular beam epitaxy and magnetron sputtering within an ultra-high vacuum cluster. Nb films deposited at varying p…
Andreev reflection and bound state formation in a ballistic two-dimensional electron gas probed by a quantum point contact
Hiroshi Irie, Clemens Todt, Norio Kumada +4
We study coherent transport and bound-state formation of Bogoliubov quasiparticles in a high-mobility InGaAs two-dimensional electron gas (2DEG) coupled to a sup…
