Robust operation of a GaAs tunable barrier electron pump
S. P. Giblin, M. -H. Bae, N. Kim +2
We demonstrate the robust operation of a gallium arsenide tunable-barrier single-electron pump operating with 1 part-per-million accuracy at a temperature of ~K and a pumping…

Rectification in mesoscopic AC-gated semiconductor devices
S. P. Giblin, M. Kataoka, J. D. Fletcher +6
We measure the rectified dc currents resulting when a 3-terminal semiconductor device with gate-dependent conductance is driven with an ac gate voltage. The rectified currents exhi…

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…
