Internal transitions of negatively charged magneto-excitons and many body effects in a two-dimensional electron gas
H. A. Nickel, T. M. Yeo, A. B. Dzyubenko +5
Spin-singlet and spin-triplet internal transitions of quasi-two-dimensional, negatively charged magneto-excitons (X-) and their evolution with excess electron density have been stu…

Interaction of an electron gas with photoexcited electron-hole pairs in modulation-doped GaAs and CdTe quantum wells
H. A. Nickel, T. Yeo, C. J. Meining +5
The nature of the correlated electron gas and its response to photo-injected electron-hole pairs in nominally undoped and modulation-doped multiple quantum-well (MQW) structures wa…

Internal Transitions of Two-Dimensional Charged Magneto-Excitons X-: Theory and Experiment
A. B. Dzyubenko, A. Yu. Sivachenko, H. A. Nickel +4
Internal spin-singlet and spin-triplet transitions of charged excitons X- in magnetic fields in quantum wells have been studied experimentally and theoretically. The allowed X- tra…
