摘要: Defined nanoparticle cluster arrays (NCAs) with total lateral dimensions of up to 25.4 μm by have been fabricated on top a 10 nm thin gold film using template guided self-assembly. This approach provides precise control the structural parameters in allowing systematic variation average number nanoparticles clusters (n) and edge separation (Λ) between 1
