This paper describes the research activity in progress at INRIM about graphene-based devices. This study, aimed at the realization of new quantum resistance standards, involves both the fabrication and the measurement of the devices. The various technological steps needed to obtain a characterized quantum Hall effect device on graphene will be illustrated.
A temperature-variable high accuracy (TVHAR) 10 kΩ resistor has been developed at the National Institute of Metrological Research, (INRIM), in order to transfer the traceability to high accuracy multifunction instruments used in the accredited calibration laboratories. The TVHAR consists of ten 100 kΩ nominal value resistors inserted in a copper block and connected in a parallel configuration. The...
