  Low-dimensional free-standing aggregates of bare gold clusters are studied by
the molecular dynamics simulation. Icosahedra of 55 and 147 atoms are
equilibrated at T=300 K. Then, their one- and two-dimensional assemblies are
investigated. It is found that icosahedra do not coalescence into large drops,
but stable amorphous nanostructures are formed: nanowires for one-dimensional
and nanofilms for two-dimensional assemblies. The high-temperature stability of
these nanostructures is also investigated.
