Two-dimensional metal-chalcogenide films in tunable optical microcavities
S. Schwarz, S. Dufferwiel, P. M. Walker +12
Quasi-two-dimensional (2D) films of layered metal-chalcogenides have attractive optoelectronic properties. However, photonic applications of thin films may be limited owing to weak…
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.…
Effect of the GaAsP shell on optical properties of self-catalyzed GaAs nanowires grown on silicon
O. D. D. Couto, D. Sercombe, J. Puebla +9
We realize growth of self-catalyzed core-shell GaAs/GaAsP nanowires (NWs) on Si substrates using molecular-beam epitaxy. Transmission electron microscopy (TEM) of single GaAs/GaAsP…
