title: Fabrication of heterogeneous binary arrays of nanoparticles via colloidal lithography.
abstract: Heterogeneous binary arrays of metallic nanoparticles have been constructed by consecutively depositing gold and silver into monolayers of hexagonally close-packed latex spheres at the incidence angles of 15 and -15 degrees, followed by removal of the colloidal masks. The present approach is independent of the chemical nature of both colloidal masks and deposition materials. The pattern feature of the resulting binary nanoparticle arrays is dependent on the colloidal mask registry.
