Abstract
Strong enhancement of exciton absorption peaks at low applied voltage without redshift of the absorption edge, which is attributed to e1hh2 and e2hh1 transitions, was observed at room temperature in a structure composed of five-step asymmetric coupled quantum well (FACQW). The measurement results agree well with our numerical analysis results.Keywords
