Abstract

The work is devoted to the study of noise characteristics of curved Hall bars based on InGaAs/AlGaAs/GaAs semiconductor heterostructures. The noise spectral density S N (f) was investigated experimentally and the magnetic field detection limit B N of a flat and similar Hall bar rolled in a tube was defined. The low-frequency spectra of 1/f noise were studied and the dimensionless Hooge noise parameter α H was determined. The ability to use the curved Hall bars in the devices for measuring weak magnetic fields (<1 μT) was predicted.
