QuAHMET
This project focuses on developing quantum metrology methods for high-frequency electrical measurements, with applications in telecommunications and the electronics industry.
This project focuses on developing quantum metrology methods for high-frequency electrical measurements, with applications in telecommunications and the electronics industry.
The Quantum Hall Effect (QHE) forms the basis for the realisation of the Primary Resistance Standard (PRS) – the “gold standard” of electrical metrology.
QHE devices currently require low temperatures and high magnetic fields, limiting their use outside national metrology institutes.
The Quantum Anomalous Hall Effect (QAHE) offers the possibility of overcoming these limitations while maintaining the unparalleled accuracy expected from the PRS. Gaining deeper knowledge of QAHE devices is essential to accelerate the development of a quantum electrical metrology toolbox that will enable the universal use of quantum electrical SI standards.
The project will develop, characterise and evaluate thin films for QAHE and the devices manufactured from them, leading to a detailed metrological assessment from sub-kelvin to above 1 K, for currents from below 100 nA to above 1 μA, and across a wide range of external magnetic fields of up to several tesla.
