Josephson Effect in NbS van der Waals Junctions
Chuanwen Zhao, Xin Yi, Qiao Chen +2
Van der Waals (vdW) Josephson junctions can possibly accelerate the development of advanced superconducting device that utilizes the unique properties of two-dimensional (2D) trans…
A low-noise on-chip coherent microwave source
Chengyu Yan, Juha Hassel, Visa Vesterinen +5
The scaleup of quantum computers operating in the microwave domain requires advanced control electronics, and the use of integrated components that operate at the temperature of th…
Broadband Tunable Phase Shifter For Microwaves
Jinli Zhang, Tianyi Li, Roope Kokkoniemi +8
We implement a broadly tunable phase shifter for microwaves based on superconducting quantum interference devices (SQUIDs) and study it both experimentally and theoretically. At di…
Demonstration of electron focusing using electronic lenses in low-dimensional system
Chengyu Yan, Michael Pepper, Patrick See +3
We report an all-electric integrable electron focusing lens in n-type GaAs. It is shown that a pronounced focusing peak takes place when the focal point aligns with an on-chip dete…
Thermoelectric property of a one dimensional channel in the presence of a transverse magnetic field
Chengyu Yan, Michael Pepper, Patrick See +3
We studied the thermal conduction through a quantum point contact (QPC), defined in GaAs-AlGaAs heterostructure, in the presence of a transverse magnetic field. A shift in the posi…
Magnetoresistance in an electronic cavity coupled to one-dimensional systems
Chengyu Yan, Sanjeev Kumar, Patrick See +5
In this work, we performed magnetoresistance measurement in a hybrid system consisting of an arc-shaped quantum point contact (QPC) and a flat, rectangular QPC, both of which toget…
