Abstract
We observed the spin-half Kondo effect for a single uncapped large InAs self-assembled quantum dot at zero and at a high magnetic field. At zero field we observed the standard Kondo effect. The high-field Kondo effect appears only when the first and second spin-resolved Landau states become degenerate because of the large Zeeman effect, which we confirmed from the magnetic field dependence of the Kondo effect.Keywords
