摘要

我们已经生产并表征了适合在低于8 T的场和1.2-1.5 K的温度下进行精确量子霍尔电阻(QHR)测量的器件。我们使用市售的室温直流电流比较器桥对QHR器件与线绕电阻进行了准确的比较。这两个结果表明，有可能组装一个准确，但相对便宜和操作简单的QHR标准。

Towards a cheaper, simpler quantized Hall resistance standard

We have produced and characterised devices suitable for accurate quantum Hall resistor (QHR) measurements at fields below 8 T, and temperatures of 1.2-1.5 K. We have made accurate comparisons of QHR devices with wirewound resistors using commercially available room-temperature dc current-comparator bridges. These two results imply that it is possible to assemble an accurate, but relatively cheap and simple to operate, QHR standard.
