Dynamic HAADF-STEM Observation of a Single-Atom Chain as the Transient State of Gold Ultrathin Nanowire Breakdown
Ultrathin
chemically grown gold nanowires undergo irremediable
structural modification under external stimuli. Thanks to dynamic
high-angle annular dark-field imaging, electron-beam-induced damage
was followed, revealing the formation of linear chains of gold atoms
as well as reactive clusters on the side, opening fascinating prospects
for applications in both catalysis and electronic transport

Growth and Self-Assembly of Ultrathin Au Nanowires into Expanded Hexagonal Superlattice Studied by in Situ SAXS
We report the self-assembly of gold
nanowires into hexagonal superlattices
in liquid phase followed by in situ small-angle X-ray scattering and
give new insights into their growth mechanism. The unprecedented large
interwire distance of 8 nm strongly suggests the stabilization of
the ultrathin gold nanowires by a ligandās double layer composed
of oleylamine and oleylammonium chloride. The one-dimensional growth
is discussed, opening perspectives toward the control growth and self-assemblies
of metallic nanowires
