Trion magnetic polarons in (Cd,Mn)Te/(Cd,Mn,Mg)Te quantum wells

Optical imaging of trion diffusion and drift in GaAs quantum wells

TRION-BASED OPTICAL PROCESSES IN SEMICONDUCTOR QUANTUM WELLS by THOMAS KENDRICK BALDWIN A DISSERTATION

Original approval signatures are on file with the University of Oregon Graduate School. In a semiconductor, negative charge is carried by conduction-band electrons and positive charge is carried by valence-band holes. While charge transport properties can be understood by considering the motion of these carriers individually, the optical properties are largely determined by their mutual interac...

Magnetic properties of HgTe quantum wells

Using analytical formulas as well as a finite-difference scheme, we investigate themagnetic field dependence of the energy spectra and magnetic edge states of HgTe/CdTe-based quantum wells in the presence of perpendicular magnetic fields and hard walls for the band-structure parameters corresponding to the normal and inverted regimes. Whereas one can not find counterpropagating, spin-polarized ...

Trion X+ in vertically coupled type II quantum dots in threading magnetic field

We analyze the energy spectrum of a positively charged exciton confined in a semiconductor heterostructure formed by two vertically coupled, axially symmetrical type II quantum dots located close to each other. The electron in the structure is mainly located inside the dots, while the holes generally move in the exterior region close to the symmetry axis. The solutions of the Schrödinger equati...
