Professor Dobrowolska-Furdyna's research interests involve magnetospectroscopy of semiconductor heterostructures, i.e., systems composed of ultrathin layers of different semiconductor compounds, with thicknesses in the range of a few atomic monolayers. Such an arrangement leads to new effects which are of great interest both in fundamental physics and in device applications. Magnetospectroscopic studies provide important insights into the electronic structures and optical properties of these novel systems.
Most recently her interest has focused on structures in which some of the layers are magnetic which also affords the possibility of investigating the effect of reduced dimensionality on magnetic properties of such structures.
