Project: Graphene impedance quantum standard

Acronym GIQS (Reference Number: 18SIB07)
Duration 01/06/2019 - 31/05/2022
Project Topic The marketability of electronic products relies on quantifications of voltage, resistance, and impedance. While the major metrology institutes offer ‘gold standard’ traceability for voltage and resistance, by applying Josephson (JE) and quantum Hall effects (QHE), calibrating impedance traceable to the QHE is costly. Cheaper routes to traceability for impedance quantities (ohm, farad, and henry), linked to the defining constants of the revised SI units, would boost supply chains by enabling affordable, traceable measurement services, by a broader range of providers. The project will establish a new primary standard for impedance, linked to the revised SI Units, by exploiting quantum effects of graphene. Novel digital impedance measurement bridges combined with a simpler cooling method will result in a graphene-based quantum Hall resistance device. This will enable a cheaper and easier-to-operate primary standard, and more affordable and improved measurement services. The project will also help link other electrical units to the revised SI units, while new devices will become possible in the technology sector, for faster, more sensitive measurement methods.
