摘要
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.
