Synthesis and Applications of III-V Nanowires
TL;DR: The way in which several innovative synthesis methods constitute the basis for the realization of highly controlled nanowires is reviewed, and one of how the different families ofnanowires can contribute to applications is combined.

Enabling near-atomic–scale analysis of frozen water
Ayman A. El-Zoka,Se-Ho Kim,Sylvain Deville,Roger C. Newman,Leigh T. Stephenson,Baptiste Gault,Baptiste Gault +6 more
TL;DR: In this article, the authors used atom probe tomography to analyze frozen liquids in 3D with subnanometer resolution, using nanoporous gold as a sample preparation strategy and showed that the gold-ice interface reveals a substantial increase in the solute concentrations across the interface.

TL;DR: In this paper, the nanoscale chemical mapping of GaAs/Al-GaAs core-shell nanowires is analyzed in 3D by atom probe tomography (APT) to confirm that Al atoms tend to segregate within the AlGaAs shells towards the vertices of the hexagons defining the nanowire cross section.

Dopant, composition and carrier profiling for 3D structures
Wilfried Vandervorst,Claudia Fleischmann,Janusz Bogdanowicz,Alexis Franquet,Umberto Celano,Kristof Paredis,A. Budrevich +6 more
TL;DR: In this article, the authors evaluate the performance of 3D metrology tools and concepts for 3D devices and structures, and assess not only the ability to achieve 3D spatial resolution, but also the physical property which is probed, i.e., dopants versus carriers, as well as the complexity of the method used because this impacts on success rate, turn-around time, throughput, automation etc.

Controlled polytypic and twin-plane superlattices in iii-v nanowires.
Philippe Caroff,Kimberley A. Dick,Jonas Johansson,Maria E. Messing,Knut Deppert,Lars Samuelson +5 more
TL;DR: By selectively tuning the crystal structure, this work fabricates highly reproducible polytypic and twin-plane superlattices within single nanowires, which could lead to bandgap engineering and novel electronic behaviour.

TL;DR: It is shown that the crystal structure of indium phosphide (InP) nanowires can be controlled by using impurity dopants, and it is demonstrated that zinc decreases the activation barrier for two-dimensional nucleation growth of zinc-blende InP and therefore promotes crystallization of the InPnanowires in the zinc- Blende, instead of the commonly found wurtzite, crystal structure.

Direct measurement of dopant distribution in an individual vapour–liquid–solid nanowire
Daniel E. Perea,Eric R. Hemesath,Edwin J. Schwalbach,Jessica L. Lensch-Falk,Peter W. Voorhees,Lincoln J. Lauhon +5 more
TL;DR: The first direct measurements of dopant concentrations in arbitrary regions of individual nanowires are reported, finding that differences in precursor decomposition rates between the liquid catalyst and solid nanowire surface give rise to a heavily doped shell surrounding an underdoped core.
