Electrometry using the quantum Hall effect in a bilayer 2D electron system
arXiv:1003.5017 · doi:10.1063/1.3428778
Abstract
We discuss the development of a sensitive electrometer that utilizes a two-dimensional electron gas (2DEG) in the quantum Hall regime. As a demonstration, we measure the evolution of the Landau levels in a second, nearby 2DEG as the applied perpendicular magnetic field is changed, and extract an effective mass for electrons in GaAs that agrees within experimental error with previous measurements.
