Spontaneous nucleation and growth of GaN nanowires: Fundamental role of crystal polarity
Sergio Fernández-Garrido, Xiang Kong, Tobias Gotschke +4
We experimentally investigate whether crystal polarity affects the growth of GaN nanowires in plasma-assisted molecular beam epitaxy and whether their formation has to be induced b…
Polarity-induced selective area epitaxy of GaN nanowires
Ziani de Souza Schiaber, Gabriele Calabrese, Xiang Kong +6
We present a conceptually novel approach to achieve selective area epitaxy of GaN nanowires. The approach is based on the fact that these nanostructures do not form in plasma-assis…
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…
