Abstract :
The effect of electric field on the photoluminescence (PL) from quantum dots (QDs) is investigated in this work. The results of PL measurements from self-organized QDs InGaAs/GaAs embedded in a field-effect structure are presented. The lineshape changes, which accompany the QDs quenching are discussed in terms of thermal evaporation and tunneling of carriers out of the QDs. The results of time-resolved PL in the biased structure are also presented and discussed.
