| Zusammenfassung | Optical transitions in self-assembled InAs/AlAs quantum dots were investigated by photoluminescence and photoluminescence excitation spectroscopy. In photoluminescence we found below about 1.8 eV emission from quantum dots whereas above appr. 1.8 eV electrons from the AlAs X-band are involved. Photoluminescence excitation spectra show polaron states with a phonon energy of 31 meV of an individual InAs dot. |
