Abstract
The frequency dependence of the quantized Hall resistance at alternating current results from capacitive losses inside the sample as well as between the sample and external parts. In this joint effort we report on ac quantum Hall measurements of a graphene-based Hall bar using superconducting contacts and a new contact design approach.Proceedings Title
