Journal ArticleDOI
Ultrahigh strength single crystalline nanowhiskers grown by physical vapor deposition.
TL;DR: Tensile tests performed in situ in a focused-ion beam scanning electron microscope on Cu nanowhiskers reveal strengths close to the theoretical upper limit and confirm that the properties of nanomaterials can be engineered by controlling defect and flaw densities.
Journal ArticleDOI
Growth Mechanism of Self-Catalyzed Group III−V Nanowires
Bernhard Mandl,Julian Stangl,Emelie Hilner,Alexei Zakharov,Karla Hillerich,Anil W. Dey,Lars Samuelson,Günther Bauer,Knut Deppert,Anders Mikkelsen +9 more
TL;DR: By combining a series of growth experiments using metal−organic vapor phase epitaxy, as well as detailed in situ surface imaging and spectroscopy, this work gains deeper insight into nucleation and growth of self-seeded III−V nanowires.
Journal ArticleDOI
Periodically Changing Morphology of the Growth Interface in Si, Ge, and GaP Nanowires
C.-Y. Wen,Jerry Tersoff,Karla Hillerich,Mark C. Reuter,Jeung Hun Park,Suneel Kodambaka,Eric A. Stach,Frances M. Ross +7 more
TL;DR: It is shown that a nonplanar growth interface is, in fact, a general phenomenon and an explicit model for this structure is developed that agrees well with experiment and shows that the oscillations provide a direct visualization of catalyst supersaturation.
Journal ArticleDOI
Atomic-Scale Variability and Control of III-V Nanowire Growth Kinetics
Yi-Chia Chou,Yi-Chia Chou,Karla Hillerich,Jerry Tersoff,Mark C. Reuter,Kimberly A. Dick,Frances M. Ross +6 more
TL;DR: A growth model is derived showing that this unexpected variation in local growth kinetics reflects the very different supply pathways of the V and III species, and under which conditions the growth rate can be controlled precisely at the atomic level.
Journal ArticleDOI
The use of gold for fabrication of nanowire structures
TL;DR: In this article, the authors identify the different types of gold particles used to initiate nanowire growth, namely gold particles made from thin films, gold particles defined by lithographic methods, colloidal gold particles and aerosol-generated gold particles.
