Molecular Beam Epitaxy of GaN Nanowires on Epitaxial Graphene
Sergio Fernández-Garrido, Manfred Ramsteiner, Guanhui Gao +10
We demonstrate an all-epitaxial and scalable growth approach to fabricate single-crystalline GaN nanowires on graphene by plasma-assisted molecular beam epitaxy. As substrate, we e…
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…
X-ray scattering study of GaN nanowires grown on Ti/AlO by molecular beam epitaxy
Vladimir M. Kaganer, Oleg V. Konovalov, Gabriele Calabrese +5
GaN nanowires (NWs) grown by molecular beam epitaxy on Ti films sputtered on AlO are studied by X-ray diffraction (XRD) and grazing incidence small-angle X-ray scatteri…
Radius-Dependent Homogeneous Strain in Uncoalesced GaN Nanowires
G. Calabrese, D. van Treeck, V. M. Kaganer +6
We investigate the strain state of ensembles of thin and nearly coalescence-free self-assembled GaN nanowires prepared by plasma-assisted molecular beam epitaxy on Ti/AlO$_{3…
Low-voltage 2D materials-based printed field-effect transistors for integrated digital and analog electronics on paper
Silvia Conti, Lorenzo Pimpolari, Gabriele Calabrese +13
Paper is the ideal substrate for the development of flexible and environmentally sustainable ubiquitous electronic systems, which, combined with two-dimensional materials, could be…
Self-Assembled formation of long, thin, and uncoalesced GaN nanowires on crystalline TiN films
David van Treeck, Gabriele Calabrese, Jelle J. W. Goertz +4
We investigate in detail the self-assembled nucleation and growth of GaN nanowires by molecular beam epitaxy on crystalline TiN films. We demonstrate that this type of substrate al…
Molecular beam epitaxy of single crystalline GaN nanowires on a flexible Ti foil
Gabriele Calabrese, Pierre Corfdir, Guanhui Gao +5
We demonstrate the self-assembled growth of vertically aligned GaN nanowire ensembles on a flexible Ti foil by plasma-assisted molecular beam epitaxy. The analysis of single nanowi…
