We report the controlled deposition of close-packed monolayer arrays of ϳ5-nm-diam Au clusters within patterned regions on GaAs device layers, thus demonstrating guided self-assembly on a substrate which can provide interesting semiconductor device characteristics. Uniform nanometer scale ordering of the clusters is achieved by a chemical self-assembly(More)
A new strategy for encapsulating neutral nanoclusters is presented which employs surfactants with large concave headgroups and multiple contact sites. Au nanoclusters ranging from 3 to 20 nm in diameter were generated in the vapor phase and dispersed into dilute solutions of resorcinarenes 1-3, where they were stabilized for up to several months.
