Abstract
We have studied the evolution of Fano resonances with an external magn etic field, applied in the Faraday configuration; in two- and three-di mensional semiconductors, by low-temperature photoluminescence excitat ion spectroscopy. The behavior of the spectra with increasing magnetic field strength depends strongly on the dimensionality of the system: Fano resonances emerge in 3D systems, while those lines which are asym metric at zero field in 2D systems become more Lorentzian-like due to the suppression of interference paths.
