Abstract The Quantum Hall effect (QHE), a macroscopic effect of solid state physics, provides
a universal representation of the unit of resistance which depends on the elementary charge …

The cryogenic current comparator (CCC), first demonstrated nearly 40 years ago, has
become a key component of electrical metrology. It utilises a superconducting screen to …

This article describes the development of a current amplifier operating at 4.2 K designed for
very low current measurements. A cryogenic current comparator with a winding ratio of 10 …

We report the controlled integration, via dip pen nanolithography, of monolayer dots of
ferritin-based CoO nanoparticles (12 μ B) into the most sensitive areas of a microSQUID …

The sensitivity and current resolution of an overlapping tube cryogenic current comparator
(CCC) are calculated in terms of an equivalent electrical circuit model. The key features for …

We have developed a 1: 30000 winding ratio cryogenic current comparator (CCC) for
measurement of small currents, eg, generated by a single electron transport device. A …

A new resistance bridge has been built at the Laboratoire national de métrologie et d'essais
(LNE) to improve the ohm realization in the Système International (SI) of units from the …

A digital H∞ controller for a two-terminal cryogenic current comparator is designed. To this
end, a set of mathematical models covering the actual system is proposed. Simulation …

The calculation of inductances of superconducting structures like the cryogenic current
comparator (CCC) is not straightforward due to image effects and unknown current …

Dans l'optique d'une modification du système international d'unités (SI), le LNE développe
l'expérience du triangle métrologique (ETM). Cette expérience consiste à appliquer la loi …
