Analysis of Emission Dynamics of a Long Lifetime in Single InAs/GaAs Quantum Dots
Junhui Huang, Hao Chen, Zhiyao Zhuo +8
A very long lifetime emission with non-single exponential decay characteristic has been reported for single InAs/GaAs quantum dot (QD) samples, in which there exists a long-lived m…
Plasmon-field-induced Metastable States in the Wetting Layer: Detected by the Fluorescence Decay Time of InAs/GaAs Single Quantum Dots
Hao Chen, Junhui Huang, Xiaowu He +6
We report a new way to slow down the spontaneous emission rate of excitons in the wetting layer (WL) through radiative field coupling between the exciton emissions and the dipole f…
Single Photon Emission from Deep Level Defects in Monolayer WSe2
Yanxia Ye, Xiuming Dou, Kun Ding +4
We report an efficient method to observe single photon emissions in monolayer WSe2 by applying hydrostatic pressure. The photoluminescence peaks of typical two-dimensional (2D) exc…
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…
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…
