Abstract

A novel method is developed to enable the formation, positioning and patterning of individual metal nano-clusters with controllable and monodispersed sizes down to 1-2 nm-scale. Among wide range of potential applications, the nanoparticle arrays are used for deterministic synthesis of monodispersed single walled carbon nanotubes. The carbon nanotubes are grown at individually controlled locations with near one-to-one yield, reaching one of the ultimate goals of nanotube synthesis.
