Spin-Resolved Edge States around an Antidot in the Vicinity of the Quantum Hall State
arXiv:0909.1395 · doi:10.1143/JPSJ.78.124704
Abstract
We have investigated spin-related effects on the electronic transport in a single antidot system in the vicinity of the quantum Hall state where two edge states with different spins of the lowest Landau level are formed around the antidot. The conductance exhibits the paired Aharonov-Bohm (AB) oscillations. Using a tilted magnetic field technique, we have observed the evolution of the oscillations with the total magnetic field and a concomitant change in the source-drain bias dependence of the differential conductance. From the observation, we extract the effect of the Zeeman energy on the AB oscillations.
