We find that the spin of an electron photo-created in such a quantum dot can be efficiently oriented by a quasi-resonant circularly-polarized excitation. For the electron spin levels which are made quasi-degenerate by a magnetic field compensating the exchange interaction $\\Delta_e$ with A$^0$, there is however a full depolarization due the aniso","authors_text":"A.
