Traceable precision pA direct current measurements with the ULCA
Hansjörg Scherer, Gerd-Dietmar Willenberg, Dietmar Drung +2
A standard method for picoammeter calibrations is the capacitor charging technique, which allows generating traceable currents in the sub-nA range. However, its accuracy is limited…

Precision quantization of Hall resistance in transferred graphene
Mirosław Woszczyna, Miriam Friedemann, Martin Götz +4
We show that quantum resistance standards made of transferred graphene reach the uncertainty of semiconductor devices, the current reference system in metrology. A large graphene d…
