SC-1 etching of Nb and TiN thin films

SC-1 etching of Nb and TiN thin films

Abstract Dry etching techniques, ubiquitous in microelectronics fabrication, often result in challenging levels of undesired collateral plasma-induced damage. In this work, we demonstrate a wet etchin…

Spontaneous supercurrents and vortex depinning in two-dimensional arrays of 𝜑0 Josephson junctions

Spontaneous supercurrents and vortex depinning in two-dimensional arrays of 𝜑0 Josephson junctions

Abstract Two-dimensional arrays of ballistic Josephson junctions are important as model systems for synthetic quantum materials. Here, we investigate arrays of multiterminal junctions which exhibit a …

Superconducting junctions with flat bands

Superconducting junctions with flat bands

Abstract We analyze the properties of flat-band superconductor junctions that behave differently from ordinary junctions containing only metals with Fermi surfaces. In particular, we show how in the t…

Magnetoelectric effects in diffusive two-dimensional superconductors studied by the nonlinear 𝜎 model

Magnetoelectric effects in diffusive two-dimensional superconductors studied by the nonlinear 𝜎 model

Abstract We describe a numerical approach to modeling magnetoelectric effects generated by spin-orbit coupling in inhomogeneous diffusive two-dimensional (2D) superconductors. It is based on direct mi…

Superconducting diode effect in diffusive superconductors and Josephson junctions with Rashba spin-orbit coupling

Superconducting diode effect in diffusive superconductors and Josephson junctions with Rashba spin-orbit coupling

Abstract We characterize the superconducting diode effect (SDE) in two-dimensional diffusive structures with Rashba spin-orbit coupling using the quasiclassical formalism. We consider both homogeneous…

Wafer-scale CMOS-compatible graphene Josephson field-effect transistors

Wafer-scale CMOS-compatible graphene Josephson field-effect transistors

Abstract Electrostatically tunable Josephson field-effect transistors (JoFETs) are one of the most desired building blocks of quantum electronics. Applications of JoFETs range from parametric amplifie…

Link between supercurrent diode and anomalous Josephson effect revealed by gate-controlled interferometry

Link between supercurrent diode and anomalous Josephson effect revealed by gate-controlled interferometry

Abstract In Josephson diodes the asymmetry between positive and negative current branch of the current-phase relation leads to a polarity-dependent critical current and Josephson inductance. The super…

Nonreciprocal Josephson Linear Response

Nonreciprocal Josephson Linear Response

Abstract We consider the finite-frequency response of multiterminal Josephson junctions and show how nonreciprocity in them can show up at linear response, in contrast to the static Josephson diodes f…
