Abstract

The quantum Hall effect (QHE), and devices reliant on it, will continue to serve as the foundation of the ohm while also expanding its territory into other SI derived units. The foundation, evolution, and significance of all of these devices exhibiting some form of the QHE will be described in the context of optimizing future electrical resistance standards. As the world adapts to using the quantum SI, it remains essential that the global metrology community pushes forth and continues to innovate and produce new technologies for disseminating the ohm and other electrical units.

摘要

量子霍尔效应(QHE)及其相关器件将继续作为欧姆的基础,同时还会将其领域扩展到其他国际单位制(SI)导出单位。所有呈现某种形式量子霍尔效应的这些器件的基础、演变和意义将在优化未来电阻标准的背景下进行描述。随着世界适应使用量子化国际单位制,全球计量学界继续推进并不断创新,生产用于传播欧姆和其他电学单位的新技术仍然至关重要。
