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…

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…
