Monitoring the formation of nanowires by line-of-sight quadrupole mass spectrometry: a comprehensive description of the temporal evolution of GaN nanowire ensembles

Sergio Fernández-Garrido, Johannes K. Zettler, Lutz Geelhaar +1

We use line-of-sight quadrupole mass spectrometry to monitor the spontaneous formation of GaN nanowires on Si during molecular beam epitaxy. We find that the temporal evolution of…

Self-regulated radius of spontaneously formed GaN nanowires in molecular beam epitaxy

Sergio Fernández-Garrido, Vladimir M. Kaganer, Karl K. Sabelfeld +5

We investigate the axial and radial growth of GaN nanowires upon a variation of the Ga flux during molecular beam epitaxial growth. An increase in the Ga flux promotes radial growt…

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…

High-temperature growth of GaN nanowires by molecular beam epitaxy: toward the materials quality of bulk GaN

J. K. Zettler, C. Hauswald, P. Corfdir +5

In molecular beam epitaxy, the spontaneous formation of GaN nanowires on Si(111) substrates at elevated temperatures is limited by the long incubation time that precedes nanowire n…

A comprehensive diagram to grow InAlN alloys by plasma-assisted molecular beam epitaxy

S. Fernández-Garrido, Ž. Gačević, E. Calleja

Indium incorporation and surface morphology of InAlN layers grown on (0001)GaN by plasma-assisted molecular beam epitaxy were investigated as a function of the impinging In flux an…
