Extended excitons and compact helium-like biexcitons in type-II quantum dots

Autor: Bansal, Bhavtosh, Godefroo, S., Hayne, M., Ribeiro, G. Medeiros, Moshchalkov, V. V.

We have used magneto-photoluminescence measurements to establish that InP/GaAs quantum dots have a type-II (staggered) band alignment. The average excitonic Bohr radius and the binding energy are estimated to be 15nm and 1.5 meV respectively. When co

Excitonic Mott transition in type-II quantum dots

Autor: Bansal, Bhavtosh, Hayne, M., Geller, M., Bimberg, D., Moshchalkov, V. V.

Photoluminescence spectra measured on a type-II GaSb/GaAs quantum dot ensemble at high excitation power indicate a Mott transition from the low density state comprising of spatially-indirect excitons to a high density electron-plasma state. Under the

High-field magneto-excitons in unstrained GaAs/AlGaAs quantum dots

Autor: Sidor, Y., Partoens, B., Peeters, F. M., Schildermans, N., Hayne, M., Moshchalkov, V. V., Rastelli, A., Schmidt, O. G.

The magnetic field dependence of the excitonic states in unstrained GaAs/AlGaAs quantum dots is investigated theoretically and experimentally. The diamagnetic shift for the ground and the excited states are studied in magnetic fields of varying orien
