Fermi-edge singularity of two dimensional electrons in asymmetric coupled double quantum wells
Materials Science & Engineering B, pp. 325-329, 1995.
We present photoluminescence (PL) and PL excitation investigations on modulation doped GaAs AlGaAs asymmetric coupled double quantum wells. A Fermi-edge singularity is observed in the emissions between the electrons in the second sub-band and the holes bound at acceptors and in the valence band. The emission related to the holes bound at ...More
