Longitudinal Impedance Measurements on Graphene QHE Devices
Abstract
This paper addresses the challenges associated with accurately measuring longitudinal impedance in a quantum Hall device. A novel bridge design capable of measuring both real and imaginary components of longitudinal impedance is introduced and applied for the first time. The measured inductance appears to be independent of both carrier density and mobility. Additionally, the inductance remains constant over the frequency range from 600 Hz to 50 kHz.
