We have studied the dimensionality dependence of the behavior of Fano resonances in the photoluminescence excitation spectra of GaAs---AlxGa1−xAs heterostructures in a magnetic field applied in the Faraday configuration. A striking difference is observed between quasi-two and quasi-three-dimensional systems: while the Fano profiles evolve into Lorentzian lineshapes in two-dimensional systems, Fano resonances emerge from the continuum in three-dimensional-systems with increasing magnetic field.

Abstract

We have studied the dimensionality dependence of the behavior of Fano resonances in the photoluminescence excitation spectra of GaAs---AlxGa1−xAs heterostructures in a magnetic field applied in the Faraday configuration. A striking difference is observed between quasi-two and quasi-three-dimensional systems: while the Fano profiles evolve into Lorentzian lineshapes in two-dimensional systems, Fano resonances emerge from the continuum in three-dimensional-systems with increasing magnetic field.
