Abstract [en]
We describe the preliminary measurement conducted to establish a baseline dataset toward a cryogen-free system for quantized Hall resistance (QHR) standard application. This paper illustrates the current state-of-the-art cryogenic system, the quantization verification and ratio measurement between an established GaAs Hall bar and a graphene-base quantum Hall array resistance standard (GQHARS). The technology comparison is carried out with a room temperature ratio bridge.
