Giant spin-dependent photo-conductivity in GaAsN dilute nitride semiconductor
A. Kunold, A. Balocchi, F. Zhao +4
A theoretical and experimental study of the spin-dependent photoconductivity in dilute Nitride GaAsN is presented. The non linear transport model we develop here is based on the ra…
Robust quantum dot state preparation via adiabatic passage with frequency-swept optical pulses
C. -M. Simon, T. Belhadj, B. Chatel +8
The energy states in semiconductor quantum dots are discrete as in atoms, and quantum states can be coherently controlled with resonant laser pulses. Long coherence times allow the…
Impact of heavy hole-light hole coupling on optical selection rules in GaAs quantum dots
Thomas Belhadj, Thierry Amand, Alejandro Kunold +8
We report strong heavy hole-light mixing in GaAs quantum dots grown by droplet epitaxy. Using the neutral and charged exciton emission as a monitor we observe the direct consequenc…
