| Zusammenfassung | What is this about? This guide provides information for the realization of the farad from the quantum Hall resistance in graphene devices by using digital impedance bridges. Who is it for? This guide is for researchers active in electrical metrology (national metrology institutes, calibration centers, metrology laboratories in the academy) who need to perform impedance measurements traceable to the International System of Units. What is its purpose? This guide provides a detailed description of how to set up a laboratory to perform measurements of artifact capacitance standards in terms of the quantized Hall resistance in graphene devices. The fabrication and characterization of graphene quantum Hall effect devices, the cryogenic environment required to achieve the quantization conditions, the digital impedance bridges and calibration procedures are reported. What is the prerequired knowledge? This guide is for users in research and industry who have experience with and access to the advanced techniques described herein. It is targeted at researchers having experience in electrical metrology. |
