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

We propose a new design for a 10-<formula formulatype="inline"><tex Notation="TeX">$\hbox{k}\Omega$</tex></formula> quantized Hall resistance (QHR) array device. This design realizes quantizedâ€¦ (More)

We have started to develop 1-MΩ quantum Hall array standards with GaAs/AlGaAs substrates. This 1-MΩ QHR array device consists of 88 Hall bars, and the nominal value is 1 MΩâ€¦ (More)

In this paper, quantized voltage steps were observed by driving an overdamped Josephson junction array (JJA) with current pulse trains. The current pulse trains were generated by triggering aâ€¦ (More)
