Realisation of a quantum current standard at liquid helium temperature with sub-ppm reproducibility
Stephen Giblin, Emma Mykkänen, Antti Kemppinen +7
A silicon electron pump operating at the temperature of liquid helium has demonstrated repeatable operation with sub-ppm accuracy. The pump current, approximately 168 pA, is measur…
Derivation of potential profile of a dynamic quantum dot
Nathan Johnson, Gento Yamahata, Akira Fujiwara
We report a method to derive the potential barrier profile shape in a dynamic quantum dot and show the loading statistics, and hence accuracy of electron transfer, depend significa…
Picosecond coherent electron motion in a silicon single-electron source
Gento Yamahata, Sungguen Ryu, Nathan Johnson +3
Understanding ultrafast coherent electron dynamics is necessary for application of a single-electron source to metrological standards, quantum information processing, including ele…
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…
