摘要：

We report subband resonances related to higher energy subbands in a series of GaAs/AlAs asymmetric double quantum well superlattice (ADQW-SL) systems under electric field. Various phenomena can be observed in these ADQW-SL systems, such as the Gamma-X-Gamma electron resonance and transport, hole subband resonance, phonon replica, and Gamma-Gamma anticrossings. These resonances greatly affect photoluminescence properties, photocurrent-voltage characteristics, and photocurrent impulse responses. We also investigated the X-Gamma transfer mechanism in these systems.
