We have systematically measured the electroreflectance spectra of a GaAs (7.0 nm)/Al 0.1 Ga 0.9 As (3.5 nm) superlattice at various electric fields to investigate Franz-Keldysh (FK) oscillations. In the low-field regime, we clearly observe the FK oscillations toward the low-energy side of the M 1 cr

We report on the observation of the Franz-Keldysh oscillations associated with the secondelectron and heavy-hole minibands, in which the second-electron miniband lies above the barrier potential, in a GaAs(7.0 nm)/Al 0.1 Ga 0.9 As (3.5 nm) superlattice by using electroreflectance spectroscopy. The r
