Project

More robust quantum standards with graphene

The project will further develop the use of graphene for the realization of the unit of resistance. By investigating how contact resistance and component geometry affect the quantum Hall effect, the project will generate knowledge…
Project

Ac-Realisation of Resistance with Graphene

This project aims to establish a primary realisation of ac resistance at RISE through ac measurements of the quantum Hall effect (QHE) in graphene. This will lead to a significantly reduced measurement uncertainty for ac resistanc…
Project

Programmable graphene resistance standards

The project will develop and test programmable resistance standards of graphene.
Story

World-leading electrical measurements with graphene and quantum effect

Graphene and quantum mechanical phenomena are enabling even more precise electrical measurements for industry and society. In a cleanroom in Gothenburg, researchers from RISE manufacture world-leading chips that drive this develop…
