Pseudo-monocrystalline properties of cylindrical nanowires confinedly grown by electrodeposition in nanoporous alumina templates
Four different cylindrical nanowire systems (nickel, cobalt, Co23Cu77, and multisegmented Co58Ni42/Co83Ni17 nanowires) with single-crystal-like properties were characterized by transmission electron microscopy and selected-area electron diffraction (SAED) under different tilting angles. Although t...

| description | Four different cylindrical nanowire systems (nickel, cobalt, Co23Cu77, and multisegmented Co58Ni42/Co83Ni17
nanowires) with single-crystal-like properties were characterized by transmission electron microscopy and
selected-area electron diffraction (SAED) under different tilting angles. Although these nanowires have
different chemical compositions, crystalline structures and/or diameters, they exhibit similar behaviors, which
are unexpected for ideal single-crystals. All the samples presented SAED patterns that did not experience
changes from one zone axis to another when the nanowire was tilted in a wide range of angles, exhibiting
related apparent interplanar distances that are dependent on the nanowire inclination, yielding deformed
patterns that can be unrecognizable. Moreover, face-centered cubic nanowires presented classically
forbidden reflections. These behaviors were explained by considering the characteristics of the measurement
technique and the confined template-assisted growth, which force the atoms to be accommodated in
a cylindrical volume with nanoscale dimensions, yielding the frustrated formation of stable facets and right
angles in the nanowire radial directions, together with the formation of stacking faults. |
