This paper gives the 2002 self-consistent set of values of the basic constants and conversion
factors of physics and chemistry recommended by the Committee on Data for Science and …

The quantum Hall effect (QHE) provides an invariant reference for resistance linked to
natural constants. It is used worldwide to maintain and compare the unit of resistance. The …

In view of the progress achieved in the field of the alternating current (ac) quantum Hall
effect (QHE), the Working Group of the Comité Consultatif d'Électricité et Magnétisme …

Graphene-based quantised Hall resistance standards promise high precision for the unit
ohm under less exclusive measurement conditions, enabling the use of compact …

We report on a study concerning an on-chip quantum Hall effect (QHE) circuit made of two
series arrays of two Hall bars set parallel to each other. This array, the design of which is …

By fixing two fundamental constants from quantum mechanics, the Planck constant h and the
elementary charge e, the revised “Système international”(SI) of units endorses explicitly …

Metrological investigations of the quantum Hall effect (QHE) completed by transport
measurements at low magnetic field are carried out in a-few-μ m-wide Hall bars made of …

It is theoretically possible to combine several Hall bars in arrays to define quantum
standards with perfectly quantized resistance values. We have thus developed and …

Since 1990, the quantum Hall resistance measured with direct current (dc) has been
established to represent and maintain the dc resistance unit and thereby has replaced the …
