摘要：
Coupled triple quantum-well GaAs/AlGaAs heterostructures have been designed to exhibit simultaneous electron and hole tunneling from the central well to opposite side wells at a fixed applied bias. Band offset is the critical parameter for the design of structures with simultaneous resonances. Photocurrent measurements reveal which triple quantum-well structures exhibit simultaneous resonances. A band offset ratio near 62:38 is required to correctly engineer structures with simultaneous resonances.
