Project: Quantum resistance metrology based on graphene

While quantum electrical voltage standards are widespread and easily transported, the same cannot be said for quantum resistance standards. The primary resistance standards are only available at national measurement institutes and the resulting calibrations lose precision at every link of their long chain. Graphene exhibits the quantum Hall effect at lower magnetic fields and closer to room temperature than any other material. The material could therefore help create simple and portable ‘bench-top’ systems which could be deployed more widely and easily than current resistance standards (even into industry). This would reduce the cost and inconvenience of the calibration chain. This project will use materials science and improved measurement precision to build stable graphene devices that can operate in relaxed conditions of temperature and magnetic field. These will then be used as quantum resistance standards for the electricity community.
