Improved AC quantized Hall measurements

Improved AC quantized Hall measurements

AC quantized Hall resistance (QHR) measurements have been performed with an improved probe and sample mounting system. We describe investigations of the structure of the R/sub H/ plateau versus frequency, sample configuration, sample current and temperature. We have observed R/sub xx/ minima smaller...

Zusammenfassung:AC quantized Hall resistance (QHR) measurements have been performed with an improved probe and sample mounting system. We describe investigations of the structure of the R/sub H/ plateau versus frequency, sample configuration, sample current and temperature. We have observed R/sub xx/ minima smaller than 0.02 ppm of R/sub H/.
