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…

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…
