Microscopic metallic air-bridge arrays for connecting quantum devices
Y. Jin, M. Moreno, P. M. T. Vianez +5
We present a single-exposure fabrication technique for a very large array of microscopic air-bridges using a tri-layer resist process with electron-beam lithography. The technique…
High-resolution error detection in the capture process of a single-electron pump
S. P. Giblin, P. See, A. Petrie +6
The dynamic capture of electrons in a semiconductor quantum dot (QD) by raising a potential barrier is a crucial stage in metrological quantized charge pumping. In this work, we us…
A Josephson frequency for fractionally charged anyons
M. Kapfer, P. Roulleau, M. Santin +3
Anyons occur in two-dimensional electron systems as excitations with fractional charge in the topologically ordered states of the Fractional Quantum Hall Effect (FQHE). Their dynam…
Multiplexed Charge-locking Device for Large Arrays of Quantum Devices
R. K. Puddy, L. W Smith, H. Al-Taie +7
We present a method of forming and controlling large arrays of gate-defined quantum devices. The method uses a novel, on-chip, multiplexed charge-locking system and helps to overco…
Statistical study of conductance properties in one-dimensional quantum wires focussing on the 0.7 anomaly
L. W. Smith, H. Al-Taie, F. Sfigakis +9
The properties of conductance in one-dimensional (1D) quantum wires are statistically investigated using an array of 256 lithographically-identical split gates, fabricated on a GaA…
Cryogenic on-chip multiplexer for the study of quantum transport in 256 split-gate devices
H. Al-Taie, L. W. Smith, B. Xu +7
We present a multiplexing scheme for the measurement of large numbers of mesoscopic devices in cryogenic systems. The multiplexer is used to contact an array of 256 split gates on…
