Aharonov Bohm

We have fabricated quantum rings in a GaAs/GaAlAs heterostructure 2DEG by local anodic oxidation with an atomic force microscope. In low magnetic fields we observe Aharonov-Bohm oscillations with a period of 60 mT corresponding to an effective ring diameter of 300 nm. In the high field regime, between filling factors ν = 2/3 and ν = 3, we observe Aharonov-Bohm oscillations of quantum Hall edge channels with a surprisingly large period, Δ B = 163 mT , corresponding to an edge channel around the inner diameter of the ring.

Resistance Fluctuations

We present an experimental study of four-terminal resistance fluctuations of mesoscopic samples in the quantum Hall regime. We show that in the vicinity of integer quantum Hall transitions there exist two kinds of correlations between the longitudinal and Hall resistances of the samples, one on either side of the transition region.
