Work on graphene quantum resistance standards from EMRP project GraphOhm (SIB51) has been published in Nature

Work by project partner LNE on developing a graphene device grown by chemical vapour deposition on silicon carbide for use as Quantum Hall resistance standards has been published in Nature.

Within the EMRP project 'Quantum resistance metrology based on graphene' a team of researchers at LNE and various laboratories at National Center for Scientific Research (CNRS) has found that graphene, which led to the 2010 Nobel Prize in Physics, can be used to realize a primary standard of electrical resistance based on the quantum Hall effect, which operates with state-of-the-art accuracy and in experimental conditions much more practical than that required by conventional semiconductors.

These results, published in Nature Nanotechnology on 7 September 2015, pave the way to a broader use of the universal and accurate quantum electrical standards to the benefit of Science and Industry. They also contribute to the redefinition of the International System of units, including the redefinition of the kilogram. Moreover, they proof that graphene is now mature for a very demanding application. Preliminary works were published in Nature Communications in April 2015 (Nat. Commun. 6, 6806 (2015)).
