Giant Stark effect in the emission of single semiconductor quantum dots (1011.2436v1)
Published 10 Nov 2010 in cond-mat.mes-hall, cond-mat.other, and quant-ph
Abstract: We study the quantum-confined Stark effect in single InAs/GaAs quantum dots embedded within a AlGaAs/GaAs/AlGaAs quantum well. By significantly increasing the barrier height we can observe emission from a dot at electric fields of -500 kV/cm, leading to Stark shifts of up to 25 meV. Our results suggest this technique may enable future applications that require self-assembled dots with transitions at the same energy.
