title: Structure-property relations in Au55 cluster layers studied by temperature-dependent impedance measurements.
abstract: Thin films of ligand-stabilized gold clusters, prepared from solution, exhibit quasi one-dimensional conduction behavior due to "easy paths" between well-organized grains. The stepwise construction of a defined number of layers succeeds with dithiols as linkers between clusters-the picture shows two layers so linked, with the outermost layer retaining its ligand coat. The current-voltage behavior shows linearity even at low temperatures, to indicate well-ordered structures.
