Statistical evaluation of 571 GaAs quantum point contact transistors showing the 0.7 anomaly in quantized conductance using millikelvin cryogenic on-chip multiplexing
Pengcheng Ma, Kaveh Delfanazari, Reuben K. Puddy +8
The mass production and the practical number of cryogenic quantum devices producible in a single chip are limited to the number of electrical contact pads and wiring of the cryosta…

Reconfigurable multiplex setup for high throughput electrical characterisation at cryogenic temperature
Xinya Bian, Hannah J Joyce, Charles G Smith +3
In this paper, we present a reconfigurable multiplex (MUX) setup that increases the throughput of electrical characterisation at cryogenic temperature. The setup separates the MUX…

Quantized conductance in split gate superconducting quantum point contacts with InGaAs semiconducting two-dimensional electron systems
Kaveh Delfanazari, Jiahui Li, Yusheng Xiong +11
Quantum point contact or QPC -- a constriction in a semiconducting two-dimensional (2D) electron system with a quantized conductance -- has been found as the building block of nove…
