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 config uration. A striking difference is observed between quasi-two and quasi -three-dimensional systems: while the Fano profiles evolve into Lorent zian lineshapes in two-dimensional systems, Fano resonances emerge fro m the continuum in three-dimensional-systems with increasing magnetic field.
