摘要：

We report evidence of resonances in the assisted transfer of excitons in a biased asymmetrical GaAs-(Ga,Al)As double quantum well. The excitonic transfers, i.e., the conversions of a direct exciton into a crossed one, are such that the initial and final hole locations are identical but the electron locations are different before and after the transfer. The calculated excitonic energies and transfer times provide a good description of the energy locations and intensities of the photoluminescence lines. © 1990 The American Physical Society.
