Assoc. Prof. M. Cengiz Onbaşlı, Electrical and Electronics Engineering, has been awarded funding from the European Partnership on Metrology for his project titled “Quantum Anomalous Hall Effect Materials and Devices for Metrology (QuAHMET).” QuAHMET project aims to advance beyond the limitations of traditional Quantum Hall effect (QHE) devices, which rely on low temperatures and high magnetic fields. These constraints restrict their use outside of national metrology institutes. The Quantum Anomalous Hall effect (QAHE) offers a promising alternative, maintaining the high accuracy of the primary resistance standard (PRS) without the need for extreme conditions. This project focuses on growing, characterizing, and evaluating thin films for QAHE, and developing devices from them. It includes comprehensive metrological assessments spanning temperatures from sub-Kelvin to above 1 Kelvin, currents ranging from below 100 nanoamps to above 1 microamp, and magnetic fields up to several Tesla.
