The various resonances in these structures show very different decay parameters as a function of the delay times. A comparison with theory demonstrates that the relaxation of both polarization and population are governed by spectral fluctuations. The redistribution properties of the population are directly determined.enheterostructureHeterostrukturIII-V HalbleiterIII-V semiconductorstime resolved measurementzeitaufgelöste Messung621667Exciton dephasing in quantum wells.
