Structure-Property Relations in Au55 Cluster Layers Studied by Temperature-Dependent Impedance Measurements

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...

Description
Summary: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.
