Abstract

We have employed inelastic light scattering to investigate electronic excitations of quantum dots in a magnetic field. For small magnetic fields the dispersion of the single-particle excitations (SPEs) follows the Fock–Darwin behavior. But already at moderate fields of Bgreater-or-equal, slanted0.6 T the SPEs deviate from that dispersion and follow directly the cyclotron resonance. This finding ...
