Second-order correlation function from asymmetric to symmetric transitions due to spectrally indistinguishable biexciton cascade emission
X. F. Wu, X. M. Dou, K. Ding +7
We report the observed photon bunching statistics of biexciton cascade emission at zero time delay in single quantum dots by second-order correlation function measurements under co…
Zinc-blende and wurtzite GaAs quantum dots in nanowires studied using hydrostatic pressure
Shuang Yang, Kun Ding, Xiuming Dou +8
We report both zinc-blende (ZB) and wurtzite (WZ) crystal phase self-assembled GaAs quantum dots (QDs) embedding in a single GaAs/AlGaAs core-shell nanowires (NWs). Optical transit…
Tuning exciton and biexciton transition energies and fine structure splitting through hydrostatic pressure in single InGaAs quantum dots
Xuefei Wu, Hai Wei, Xiuming Dou +10
We demonstrate that the exciton and biexciton emission energies as well as exciton fine structure splitting (FSS) in single (In,Ga)As/GaAs quantum dots (QDs) can be efficiently tun…
Temperature dependence of electron-spin relaxation in a single InAs quantum dot at zero applied magnetic field
X. M. Dou, B. Q. Sun, D. S. Jiang +2
The temperature-dependent electron spin relaxation of positively charged excitons in a single InAs quantum dot (QD) was measured by time-resolved photoluminescence spectroscopy at…
Measurements of a fast nuclear spin dynamics in a single InAs quantum dot with positively charged exciton
X. M. Dou, B. Q. Sun, D. S. Jiang +2
By using highly time-resolved spectroscopy with an alternative σ+/σ - laser pulse modulation technique, we are able to measure the fast buildup and decay times of the dynamical nuc…
