    Electron states and magnetophotoluminescence of elongated InAs/GaAs quantum dots

  • Original language description

    We have calculated the electronic structure of a single InAs/GaAs quantum dot in a perpendicular magnetic field. Considerable sensitivity of the shift of energy levels in magnetic field to a lateral elongation of the dots is demonstrated and a possibility to retrieve the elongation from magnetophotoluminescence spectra is discussed. Sensitivity analysis shows that spectra with at least two well resolved bands are needed for a reliable determination of the elongation.

    Elektronové stavy a magnetofotoluminiscence protažených kvantových teček InAs/GaAs

  • Czech description

    Byla spočtena elektronová struktura jedné kvantové tečky InAs/GaAs v kolmém magnetickém poli. Byla demonstrována značná citlivost posunu energiových hladin v magnetickém poli na laterální protažení teček a je diskutována možnost určení protažení z magnetofotoluminiscenčních spekter. Rozbor citlivosti ukazuje, že jsou k tomu třeba spektra s alespoň dvojicí dobře odlišených pásů.
