A determination of the SI value of QHR by the cross-capacitor in NIM

The determination of the SI value of quantized Hall resistance (QHR) by a cross-capacitor in NIM was completed in the spring of 1994. The SI value of QHR (i=1) was found to be R/sub H/=25812.8084(34) /spl Omega/ with an uncertainty of 0.132 ppm (1/spl sigma/). A CCC system is also being developed in...

Zusammenfassung:The determination of the SI value of quantized Hall resistance (QHR) by a cross-capacitor in NIM was completed in the spring of 1994. The SI value of QHR (i=1) was found to be R/sub H/=25812.8084(34) /spl Omega/ with an uncertainty of 0.132 ppm (1/spl sigma/). A CCC system is also being developed in NIM.
