Optical net gain measurement on AlGaN/GaN multi-quantum well
Quang Minh Thai, Sergi Cuesta, Lou Denaix +5
We present net gain measurements at room temperature in AlGaN/GaN 10-period multi-quantum well emitting at 367 nm, using the variable stripe length method. Measur…
Determination of the optimal shell thickness for self-catalysed GaAs/AlGaAs core-shell nanowires
R. Songmuang, Le Thuy Thanh Giang, J. Bleuse M. Den Hertog +2
We present a set of experimental results identifying various effects that govern the carrier dynamics of self-catalyzed GaAs/AlGaAs core-shell nanowires (NWs) grown by molecular be…
Alloy inhomogeneity and carrier localization in AlGaN sections and AlGaN/AlN nanodisks in nanowires with 240-350 nm emission
C. Himwas, M. den Hertog, Le Si Dang +2
The Al-Ga intermixing at Al(Ga)N/GaN interfaces in nanowires and the chemical inhomogeneity in AlxGa1-xN/AlN nanodisks (NDs) are attributed to the strain relaxation process. This i…
The dynamics of amplified spontaneous emission in CdSe/ZnSe quantum dots
D. O. Kundys, P. Murzyn, J. P. R. Wells +8
We have used the variable stripe technique and pump-probe spectroscopy to investigate both gain and the dynamics of amplified spontaneous emission from CdSe quantum dot structures.…
The Effects of Post-Thermal Annealing on the Emission Spectra of GaAs/AlGaAs Quantum Dots grown by Droplet Epitaxy
Pilkyung Moon, J. D. Lee, S. K. Ha +5
We fabricated GaAs/AlGaAs quantum dots by droplet epitaxy method, and obtained the geometries of the dots from scanning transmission electron microscopy data. Post-thermal annealin…
Effect of growth conditions on optical properties of CdSe/ZnSe single quantum dots
T. Makino, R. Andre, J. -M. Gerard +5
In this work, we have investigated the optical properties of two samples of CdSe quantum dots by using submicro-photoluminescence spectroscopy. The effect of vicinal-surface GaAs s…
