Influence of the Exciton Dark State on the Optical and Quantum Optical Properties of Single Quantum Dots

The optical properties of single InP/GalnP quantum dots are strongly affected by the dark exciton state. The exciton intensity and decay time are strongly reduced at low temperatures. Additionally, memory effects have been observed in second-order autocorrelation and cross-correlation measurements t...

Zusammenfassung:The optical properties of single InP/GalnP quantum dots are strongly affected by the dark exciton state. The exciton intensity and decay time are strongly reduced at low temperatures. Additionally, memory effects have been observed in second-order autocorrelation and cross-correlation measurements that last over several excitation cycles. This behavior has been simulated using a rate equation model.
