We have investigated electronic excitations in GaAs-AlxGa1-xAs quantum wires, and dots by resonance Raman spectroscopy. We find for quantum dots and quantum wires three types of excitations; single-particle, spin-density, and charge-density excitations (SPE's, SDE's, and CDE's, respectively). Our experiments show that SPE's are enhanced under conditions of extreme resonance, which indicates that ...
