A resistance bridge based on a cryogenic current comparator achieving sub- measurement uncertainties
W. Poirier, D. Leprat, F. Schopfer
A new resistance bridge has been built at the Laboratoire national de métrologie et d'essais (LNE) to improve the ohm realization in the (SI) of units from…
Practical quantum realization of the ampere from the electron charge
J. Brun-Picard, S. Djordjevic, D. Leprat +2
One major change of the future revision of the International System of Units (SI) is a new definition of the ampere based on the elementary charge \emph{e}. Replacing the former de…
Graphene surpasses GaAs/AlGaAs for the application of the quantum Hall effect in metrology
R. Ribeiro-Palau, F. Lafont, J. Brun-Picard +8
The quantum Hall effect (QHE) theoretically provides a universal standard of electrical resistance in terms of the Planck constant and the electron charge . In graphene, the…
Quantum Hall resistance standards from graphene grown by chemical vapor deposition on silicon carbide
F. Lafont, R. Ribeiro-Palau, D. Kazazis +9
Replacing GaAs by graphene to realize more practical quantum Hall resistance standards (QHRS), accurate to within in relative value, but operating at lower magnetic field…
Anomalous dissipation mechanism and Hall quantization limit in polycrystalline graphene grown by chemical vapor deposition
F. Lafont, R. Ribeiro-Palau, Z. Han +8
We report on the observation of strong backscattering of charge carriers in the quantum Hall regime of polycrystalline graphene grown by chemical vapor deposition, which alters the…
High Electron Mobility in Epitaxial Graphene on 4H-SiC(0001) via post-growth annealing under hydrogen
E. Pallecchi, F. Lafont, V. Cavaliere +4
We investigate the magneto-transport properties of epitaxial graphene single-layer on 4H-SiC(0001), grown by atmospheric pressure graphitization in Ar, followed by H2 intercalation…
