We report the investigation of electronic excitations in InGaAs self-assembled quantum dots using resonant inelastic light scattering. The dots can be charged via a gate by N = 1,[ellipsis (horizontal)],6 electrons. We observe excitations, which are identified as transitions of electrons, predominantly from the s to the p shell (s–p transitions) of the quasiatoms. We find that the s–p transition ...
