Practical realization of the ampere: single electrons and traceability of currents in the lowest range
Realization ampere

The sector designs and realizes innovative devices based on mesoscale quantum effect, and measurement setups at extremely low temperatures for the manipulation and detection of individual elementary charges.

Correspondingly, activity is ongoing on the improvement of calibration and measurement capabilities of currents in the lowest range (down to 10 fA) with new transconductance amplifier and capacitance-charging generators, with traceability to the standards of resistance and capacitance.
