Raman Spectroscopy of Quantum Dots

Schüller, Christian


We review recent resonant Raman experiments on GaAs−AlGaAs quantum dots. We were able to observe simultaneously single-particle-like electronic excitations (SPE) and collective spin-density and charge-density excitations (SDE and CDE). This allows us to determine the influence of many-particle interactions in the quantum dots. Moreover, by a detailed analysis of wave-vector and magnetic-field ...
