Popis:	In the present work, we report a calculation of the electron energy levels (1s,2p−,2p+) and the binding energies of a shallow impurity placed in the center of a circular quantum dot of a GaAs surrounded by AlGaAs in the presence of a uniform magnetic field applied perpendicularly to the plane of the dot. We also present results for the 1s−2p+ transition energy as a function of the magnetic field.
