In this paper room temperature pump-probe spectroscopy is employed to study ultrafast
absorption dynamics in type-II GaSb/GaAs quantum dots (QDs). Our results identify a strong …

Coulomb-induced recombination dynamics in magnetically doped type-IIb quantum dots

S Tarasek, WC Chou, WC Fan… - Quantum Dots and …, 2019 - spiedigitallibrary.org
We observe that the wavefunction overlap of the carriers in type-IIb quantum dots can be
controlled by magnetic doping and strongly depends on the excitation power density. We …
