PTB the NMI of Germany, coordinated and participated in several European research projects (projects like EMRP JRPs SIB51 GraphOhm , EMPIR JRPs 18SIB07 GIQS, and 20FUN03 COMET and H2020-FETPROACT-01-2018 TOCHA). PTB has long-standing experience and expertise in all relevant fields of electrical precision and quantum metrology, and particularly in the field of QHR metrology based on heterostructure, graphene, and on QAHE devices made from TI materials. In this project PTB will bring in their unique instrumentation for and expertise in QHR measurements, focusing on high-accuracy magneto-transport characterisation of QAHE devices in WP 2 and WP3.

The work will be carried out by the Working Group 2.61 Quantum Hall Effect, Resistance and Current
