摘要：

The resonant coupling of different electronic subbands between adjacent wells in GaAs-AlAs superlattices is investigated with electroluminescence (EL) spectroscopy as a function of the applied forward bias. The EL efficiency, i.e., the EL intensity normalized to the current, exhibits a resonant behavior. An efficient occupation of the second subband by sequential resonant tunneling is observed at higher bias.
