Apparatus and method for aerosol deposition of nanoparticles on a substrate

Abstract

Provided is an apparatus for aerosol deposition of nanoparticles on a substrate. The apparatus includes: an aerosol generator for generating an aerosol of micron-sized droplets, each droplet having a limited number of nanoparticles; and a deposition chamber for receiving the aerosol from the aerosol generator. The deposition chamber having an electrostatic field for attracting droplets in the aerosol to the substrate. The electrostatic field being substantially perpendicular to the substrate. The apparatus allows for films/networks of nanoparticles to be patterned on the substrate to sub-millimeter feature sizes, which allows the fabrication of transistor devices for printable electronics applications. Also provided are methods for depositing nanoparticles on a substrate and materials having networks of such nanoparticles.
