NGI, NPL and Oxford Instruments collaborate to develop a turnkey quantum Hall system for graphene characterization

A collaborative project between Oxford Instrument, the National Physical Laboratory (NPL) and the National Graphene Institute (NGI) at University of Manchester for a turnkey quantum Hall system for graphene characterization and primary resistance metrology has been successfully completed.

The project has been partially funded by the Innovate UK for development of commercial measurement system for nanotechnology applications, reducing operational costs, time and complexity. The quantum measurement system operates at cryogen free low magnetic fields and will enable primary resistance calibrations with unprecedented accuracies to be used by the national (metrology) laboratories and indusrial companies.

This is an exciting achievement by the consortium in demonstrating the industrial feasibility of using graphene and 2D materials to commercialize quantum measurement systems and enable new innovative and turnkey solutions in standard measurements and 2D materials characterization, said the Alliances Manager from Oxford Instruments NanoScience.

The system can be used directly on the factory floor, dramatically reducing the calibration traceability chain and improving the precision of electronics instrumentation.
