Abstract

Highly regular hexagonal Au particle networks were formed by annealing the hexagonal Au cells on silicon. The Au cells were found to be induced by the drying of water droplet arrays condensed on the Au solutions. Annealing was found to cause the aggregation of Au atoms to the intersections of hexagonal skeletons. It was also shown that the size of the network could be controlled to vary from 2 to 12 νm by varying the solute concentration, evaporation rate, and substrate temperature.
