The Magnetic Field

We consider eigenstates and magneto-optical transitions of free and donor-bound spin-singlet and spin-triplet charged magnetoexcitons in quasi-two-dimensional quantum wells. We show that the bright singlet state remains always bound while spin-triplet dark and bright states become unbound when the distance to the donor ion becomes smaller than certain critical values, which depend on the magnetic field strength. We demonstrate that main magneto-photoluminescence lines of free and donor-bound charged excitons exhibit very similar features. However, shake-up processes in photoluminescence of free trions are strictly prohibited. Therefore, shake-up transitions are distinct features indicating that symmetry-breaking mechanisms are present in the system.

Semiconductor Quantum Wells

We study the magnetization and the magnetic phases of II-VI-based n-doped non-magnetic-semiconductor (NMS) / narrow to wide dilute-magnetic-semiconductor (DMS) / n-doped NMS quantum wells under in-plane magnetic field. The parallel magnetic field is used as a tool, in order to achieve non-step-like density of states in these -appropriate for conduction-band spintronics- structures.
