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…
Ion irradiation-induced sinking of Ag nanocubes into substrates
Shiva Choupanian, Wolfhard Moeller, Martin Seyring +4
Ion irradiation can cause burrowing of nanoparticles in substrates, strongly depending on the material properties and irradiation parameters. In this study, we demonstrate that the…
Broadband Four-Wave Mixing Enhanced by Plasmonic Surface Lattice Resonance and Localized Surface Plasmon Resonance in an Azimuthally Chirped Grating
Abhik Chakraborty, Parijat Barman, Ankit Kumar Singh +8
Plasmonic enhancement of nonlinear light-matter interaction can be achieved via dedicated optimization of resonant plasmonic modes that are spectrally matched to the different wave…
Tailoring Nanowire Lasing Modes via Coupling to Metal Gratings
Francesco Vitale, Daniel Repp, Thomas Siefke +4
Tailoring the emission of plasmonic nanowire-based lasers represents one of the major challenges in the field of nanoplasmonics, given the envisaged integration of such devices int…
Lasing modes in ZnO nanowires coupled to planar metals
Daniel Repp, Angela Barreda, Francesco Vitale +4
Semiconductor nanowire lasers can be subject to modifications of their lasing threshold resulting from a variation of their environment. A promising choice is to use metallic subst…
Heavily doped zinc oxide with plasma frequencies in the telecommunication wavelength range
Alexander Koch, Hongyan Mei, Jura Rensberg +10
We demonstrate heavy and hyper doping of ZnO by a combination of gallium (Ga) ion implantation using a focused ion beam (FIB) system and post-implantation laser annealing. Ion impl…
