Precision measurement of an electron pump at 2 GHz
Stephen Giblin, Gento Yamahata, Akira Fujiwara +1
A well-characterised sample of silicon tunable-barrier electron pump has been operated at a frequency of 2 GHz using a custom drive waveform, generating a pump current of 320 pA. P…
Evidence for universality of tunable-barrier electron pumps
Stephen P. Giblin, Akira Fujiwara, Gento Yamahata +5
We review recent precision measurements on semiconductor tunable-barrier electron pumps operating in a ratchet mode. Seven studies on five different designs of pumps have reported…
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…
Thermal-error regime in high-accuracy gigahertz single-electron pumping
R. Zhao, A. Rossi, S. P. Giblin +5
Single-electron pumps based on semiconductor quantum dots are promising candidates for the emerging quantum standard of electrical current. They can transfer discrete charges with…
Clock-controlled emission of single-electron wavepackets in a solid-state circuit
J. D. Fletcher, M. Kataoka, H. Howe +8
We demonstrate the transmission of single electron wavepackets from a clock-controlled source through an empty high-energy edge channel. The quantum dot source is loaded with singl…
