Gate- and flux-tunable sin(2) Josephson element with proximitized Ge-based junctions
Axel Leblanc, Chotivut Tangchingchai, Zahra Sadre Momtaz +11
Hybrid superconductor-semiconductor Josephson field-effect transistors (JoFETs) function as Josephson junctions with a gate-tunable critical current. Additionally, they can feature…
From nonreciprocal to charge-4e supercurrents in Ge-based Josephson devices with tunable harmonic content
Axel Leblanc, Chotivut Tangchingchai, Zahra Sadre Momtaz +10
Hybrid superconductor(S)-semiconductor(Sm) devices bring a range of new functionalities into superconducting circuits. In particular, hybrid parity-protected qubits and Josephson d…
The influence of illumination conditions in the measurement of built-in electric field at p-n junctions by 4D-STEM
Bruno C da Silva, Zahra S Momtaz, Lucas Bruas +4
Momentum resolved 4D-STEM, also called center of mass (CoM) analysis, has been used to measure the long range built-in electric field of a silicon p-n junction. The effect of diffe…
Plasmon-Driven Hot Electron Transfer at Atomically Sharp Metal-Semiconductor Nanojunctions
Masiar Sistani, Maximilian G. Bartmann, Nicholas A. Güsken +6
Recent advances in guiding and localizing light at the nanoscale exposed the enormous potential of ultra-scaled plasmonic devices. In this context, the decay of surface plasmons to…
Programmable quantum Hall bisector: towards a novel resistance standard for quantum metrology
Zahra Sadre Momtaz, Stefan Heun, Giorgio Biasiol +1
We demonstrate a programmable quantum Hall circuit that implements a novel iterative voltage bisection scheme and allows obtaining any binary fraction of the fundamental…
Magnetocapacitance oscillations and thermoelectric effect in two-dimensional electron gas irradiated by microwaves
A. D. Levin, G. M. Gusev, O. E. Raichev +2
To study the influence of microwave irradiation on two-dimensional electrons, we apply a method based on capacitance measurements in GaAs quantum well samples where the gate covers…
Magnetoresistance of doped silicon
Antonio Ferreira da Silva, Alexandre Levine, Zahra Sadre Momtaz +2
We have performed longitudinal magnetoresistance measurements on heavily n-doped silicon for donor concentrations exceeding the critical value for the metal-non-metal transition. T…
Microwave induced nonlocal transport in two-dimensional electron system
A. D. Levin, Z. S. Momtaz, G. M. Gusev +1
We observe microwave induced nonlocal resistance in magnetotransport in single and bilayer electronic systems. The obtained results provide evidence for an edge state current stabi…
