Investigation of III-V Nanowires by Plan-View Transmission Electron Microscopy: InN Case Study
E Luna, J Grandal, E Gallardo +4
We discuss observations of InN nanowires (NWs) by plan-view high-resolution transmission electron microscopy (TEM). The main difficulties arise from suitable methods available for…
Dynamics of indirect exciton transport by moving acoustic fields
Adriano Violante, Kobi Cohen, Snežana Lazić +3
We report on the modulation of indirect excitons (IXs) as well as their transport by moving periodic potentials produced by surface acoustic waves (SAWs). The potential modulation…
Ultrafast supercontinuum fiber-laser based pump-probe scanning MOKE microscope for the investigation of electron spin dynamics in semiconductors at cryogenic temperatures with picosecond time and micrometer spatial resolution
T. Henn, T. Kiessling, W. Ossau +3
We describe a two-color pump-probe scanning magneto-optical Kerr effect (MOKE) microscope which we have developed to investigate electron spin phenomena in semiconductors at cryoge…
Effect of Interactions on Vortices in a Non-equilibrium Polariton Condensate
D. N. Krizhanovskii, D. M. Whittaker, R. A. Bradley +9
We demonstrate the creation of vortices in a macroscopically occupied polariton state formed in a semiconductor microcavity. A weak external laser beam carrying orbital angular mom…
Coupling of exciton states as the origin of their biexponential decay dynamics in GaN nanowires
Christian Hauswald, Timur Flissikowski, Tobias Gotschke +4
Using time-resolved photoluminescence spectroscopy, we explore the transient behavior of bound and free excitons in GaN nanowire ensembles. We investigate samples with distinct dia…
Second Harmonic Generation in Photonic Crystal Cavities in (111)-Oriented GaAs
Sonia Buckley, Marina Radulaski, Klaus Biermann +1
We demonstrate second harmonic generation at telecommunications wavelengths in L3 photonic crystal cavities in (111)-oriented GaAs. The second harmonic power from photonic crystal…
