Abstract

We have developed an optical-fiber-based Hall potential imaging system using the Pockels effect in GaAs/AlGaAs two dimensional electron systems (2DES) in the quantum Hall regime to investigate current distributions. The mapping of the Hall potential shows the current concentration at the bulk region of 2DES samples, where the critical current depends on the channel width sub-linearly. We report in detail the experimental techniques of the imaging system operating in high magnetic fields.
