چکیده انگلیسی
Landau levels have been theoretically investigated in a two-dimensional electron gas near a quantum dot (QD) layer. By a diagrammatical method, we have formulated the self-energy for the Landau level and deduced its relation to the AC conductivity Ïloc(Ï) in the QD layer. As an example, we have examined the density of states in the case where Ïloc(Ï) is described by AÏS(S=0.8). It is found that the Landau levels are broadened due to the interaction with the localized electrons in the QDs.
