Abstract

Intrinsic transitions of confined excitons in GaAs/AlGaAs superlattices with different barrier widths have been studied with the use of resonant far-infrared absorption under variation of magnetic field perpendicular and tilted with respect to the growth directions. Few resonances have been observed in spectra induced by FIR radiation by monitoring the changes of the ground state excitonic photoluminescence. The dominant resonances are the electron cyclotron resonance and the intrinsic 1s --> 2p. intrawell transitions of the heavy-hole excitons.
