Abstract

The quantum-confined Stark effect (QCSE) has been studied in electroluminescence (EL) spectra by using GaAs/Al0.3Gag0.7As symmetric coupled double-quantum-well (CDQW) structures under a 'forward' electric field. The Stark shift for the transition between the ground electron state nad heavy-hole state was successfully observed, and was found to be symmetrical with regard to the flat-band bias for EL and photoluminescence(PL), in which the electric field was applied in the forward and reverse directions, respectively.
