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…
Effect of the growth temperature and the AlN mole fraction on In incorporation and properties of quaternary III-nitride layers grown by molecular beam epitaxy
S. Fernández-Garrido, A. Redondo-Cubero, R. Gago +7
Indium incorporation into wurtzite (0001)-oriented InAlGaN layers grown by plasma-assisted molecular beam epitaxy was studied as a function of the growth temp…
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…
Growth kinetics and substrate stability during high-temperature molecular beam epitaxy of AlN nanowires
Philipp John, Mikel Gómez Ruiz, Len van Deurzen +5
We study the molecular beam epitaxy of AlN nanowires between 950 and 1215 °C, well above the usual growth temperatures, to identify optimal growth conditions. The nanowires are gro…
Large-area synthesis of ferromagnetic FeGeTe/graphene van der Waals heterostructures with Curie temperature above room temperature
H. Lv, A. da Silva, A. I. Figueroa +14
Van der Waals (vdW) heterostructures combining layered ferromagnets and other two-dimensional (2D) crystals are promising building blocks for the realization of ultra-compact devic…
Control over epitaxy and the role of the InAs/Al interface in hybrid two-dimensional electron gas systems
E. Cheah, D. Z. Haxell, R. Schott +12
In-situ synthesised semiconductor/superconductor hybrid structures became an important material platform in condensed matter physics. Their development enabled a plethora of novel…
