Project: Quantum realisation of the SI ampere
The ampere is the SI base unit of electric current. In the proposed redefinition for 2018, the ampere will be based on the value of the elementary charge, a fundamental physical constant that is the magnitude of the charge on an electron. To ensure that the new ampere can be directly realised, methods are needed that can accurately and reliably generate an electric current by controlling the flow of individual electrons. One practical method for achieving this is to use single-electron sources that generate currents by introducing just one electron at a time into a circuit. This project, built on the achievements of EMRP project SIB07 Qu-Ampere will develop capabilities for the fabrication, testing and validation of single-electron sources. These capabilities will be used to support the ampere redefinition, and will be available for industrial users to calibrate their small-current measurement devices and instruments to ensure consistency in traceable current measurements.
