The field of metrological science strives for continuous improvement in precision and reproducibility, a goal only achievable by exploiting the fundamental constants of nature. In electrical metrology, both voltage (V) and resistance (R) standards have reached this milestone, but not current (I). We aim to develop novel self-referenced nanoelectronic charge-pump devices that can generate a highly accurate, error-detectable output current utilising Australian-developed silicon-based single-electron transistor technology. We will undertake high-precision measurements in collaboration with leading European standards institutes and researchers, establishing the technological basis for a new world current standard that is reproducible worldwide.

生物科学领域致力于不断提高精度和可重复性，这一目标只有通过利用自然界的基本常数才能实现。在电气计量中，电压（V）和电阻（R）标准都达到了这一里程碑，但电流（I）标准还没有达到。我们的目标是开发新的自参考纳米电子电荷泵设备，可以产生一个高度准确的，错误可检测的输出电流，利用澳大利亚开发的硅基单电子晶体管技术。我们将与欧洲领先的标准机构和研究人员合作进行高精度测量，为全球范围内可复制的新的世界通用标准奠定技术基础。
