    Keywords : optical spin injection; optical orientation spectroscopy; magnetic field; Landau level; hyperfine interaction; dynamic nuclear polarization; InAs GaAs quantum dots;

    Abstract : Optical spin injection in InAs/GaAs quantum dots (QDs) structures under cryogenic temperature has been investigated in this work using continuous-wave optical orientation spectroscopy. Circularly polarized luminescence from trions in the QDs was used as a measure for the degree of spin polarization of the carriers in the QD ground states. READ MORE
