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 …

A quantum Hall array resistance standard (QHARS) device with a nominal value close to 10
kΩ on the i= 2 plateau has been developed on a GaAs/AlGaAs heterosubstrate. This …

New quantum Hall array resistance standards (QHARS) with nominal values in the range
from RK/200 to 50R K (i= 2 plateau) have been developed (RK is the von Klitzing constant) …

Quantum Hall effect (QHE) is the basis of modern resistance metrology. In quantum Hall
array resistance standards (QHARS), several individual QHE elements, each one with the …

We fabricated and evaluated a 1 MΩ quantum Hall array device with GaAs/AlGaAs
substrates. This 1 MΩ quantized Hall resistance array device consists of 88 Hall bars, and its …

Quantum Hall array resistance standards (QHARSs) are integrated circuits composed of
interconnected quantum Hall effect elements that allow the realization of virtually arbitrary …

We report precision measurements of a 1 MΩ quantum Hall resistance array made of
GaAs/AlGaAs heterostructure. The quantized Hall array resistance at filling factor 2 is directly …

The circuit properties of networks which include multiterminal quantum Hall‐effect (QHE)
devices are discussed. It is shown that QHE devices can be placed in a series or in parallel …

We present detailed measurements of the temperature dependence of the Hall and
longitudinal resistances on a quantum Hall device [(GaAs (7)] which has been used as a …

We propose a new design for a 10-kΩ quantized Hall resistance (QHR) array device. This
design realizes quantized resistance values that approach decade values with fewer Hall …
