We demonstrate that resonant excitation of CdMnTe self-assembled quantum dots creates an ensemble of spin-polarized magnetic polarons at B=0 T. The strong spatial confinement characteristic of quantum dots significantly increases the stability of magnetic polarons so that the optically-induced spin alignment is observed for temperatures >120 K. © 2004 American Institute of Physics.

    We carry out Si doping in InAs/GaAs quantum dots (QDs) by selecting appropriate steps of the self-assembling growth process. The self-assembling growth process of QDs consists of nucleation, assembling, self-limiting, and dissolving steps. The electrical conductivity of the QDs doped at the...

    A quantitatively thermodynamic model has been established to address the problem of the wetting layer evolution upon the quantum dots (QDs) self-assembly based on the embedded islands. It was found that the mismatch induced by the embedded islands breaks the balance of the strain energies...

    The traditional colloidal routes of fabrication of II-VI semiconductor quantum dots have been difficult to integrate with silicon technology.

    The authors report about the x-ray investigation of InAs/GaAs(001) quantum dot systems grown with varying amount of deposited InAs. It is shown that the intermixing induced composition of investigated quantum dots remains constant within the whole probed InAs deposition region. It is found that...

    The onset of strain relaxation and induced defects in InAs0.94Sb0.06 quantum dots are investigated. We show that the relaxation causes partial carrier depletion in the dots and drastic carrier depletion in the top GaAs layer due to the introduction of two defect traps at 0.35 and 0.64 eV. This...
