MESOSCOPIC SELF-ASSEMBLY OF GOLD ISLANDS AN DIBLOCK-COPOLYMER FILMS

We describe the fabrication and characterization of self-assembled gol d island arrays on diblock-copolymer thin films. The natural tendency of these polymers to form ordered phases is used to induce selective a ggregation of evaporated gold metal during an annealing process. We ob tain well-defined, nanoscale island arrays aligned with one of the cop olymer blocks. Near perfect segregation is achieved between the two do mains. Two types of diblock-copolymer systems are discussed, together with the resulting island patterns.
