Observation of dielectrically confined excitons in ultrathin GaN nanowires up to room temperature
Johannes K. Zettler, Pierre Corfdir, Christian Hauswald +10
The realization of semiconductor structures with stable excitons at room temperature is crucial for the development of excitonics and polaritonics. Quantum confinement has commonly…
Nature of excitons bound to inversion domain boundaries: Origin of the 3.45-eV luminescence lines in spontaneously formed GaN nanowires on Si(111)
Carsten Pfüller, Pierre Corfdir, Christian Hauswald +9
We investigate the 3.45-eV luminescence band of spontaneously formed GaN nanowires on Si(111) by photoluminescence and cathodoluminescence spectroscopy. This band is found to be pa…
Macro- and micro-strain in GaN nanowires on Si(111)
Bernd Jenichen, Oliver Brandt, Carsten Pfueller +3
We analyze the strain state of GaN nanowire ensembles by x-ray diffraction. The nanowires are grown by molecular beam epitaxy on a Si(111) substrate in a self-organized manner. On…
Residual disorder and diffusion in thin Heusler alloy films
Bernd Jenichen, Jens Herfort, Thomas Hentschel +4
Co2FeSi/GaAs(110) and Co2FeSi/GaAs(111)B hybrid structures were grown by molecular-beam epitaxy and characterized by transmission electron microscopy (TEM) and X-ray diffraction. T…
