  • Abstract
    We demonstrate that the accuracy of the current quantisation in a semiconductor tunable-barrier pump is better than 1.1×10-6 at a current of 150 pA. We measure the pump current against a reference current traceable to the Josephson and quantum Hall effects. The measurement technique is described in detail, and routes for further development discussed.
