Magnetic field resilient high kinetic inductance superconducting niobium nitride coplanar waveguide resonators
Cécile Xinqing Yu, Simon Zihlmann, Gonzalo Troncoso Fernández-Bada +4
We characterize niobium nitride (NbN) coplanar waveguide resonators, which were fabricated from a 10nm thick film on silicon dioxide grown by sputter deposition. For films gr…
Improvement of the critical temperature of NbTiN films on III-nitride substrates
Houssaine Machhadani, Julien Zichi, Catherine Bougerol +7
In this paper, we study the impact of using III-nitride semiconductors (GaN, AlN) as substrates for ultrathin (11 nm) superconducting films of NbTiN deposited by reactive magnetron…
Near- and mid-infrared intersubband absorption in top-down GaN/AlN nano- and micropillars
Jonas Lähnemann, David A. Browne, Akhil Ajay +5
We present a systematic study of top-down processed GaN/AlN heterostructures for intersubband optoelectronic applications. Samples containing quantum well superlattices that displa…
A bright on-demand source of anti-bunched microwave photons based on inelastic Cooper pair tunneling
Alexander Grimm, Florian Blanchet, Romain Albert +8
The ability to generate single photons is not only an ubiquitous tool for scientific exploration with applications ranging from spectroscopy and metrology to quantum computing, but…
A self-aligned nano-fabrication process for vertical NbN-MgO-NbN Josephson junctions
A. Grimm, S. Jebari, D. Hazra +4
We present a new process for fabricating vertical NbN-MgO-NbN Josephson junctions using self-aligned silicon nitride spacers. It allows for a wide range of junction areas from 0.02…
