Abstract:
1. A method of forming a charge-trapping zone, comprising: forming a plurality of nanoparticles; after forming the nanoparticles, forming a powder comprising the nanoparticles; after forming the powder, sorting the nanoparticles by size; coating the nanoparticles with dielectric material which forms charged surfaces around the nanoparticles; transferring the nanoparticles to a liquid, and forming a dispersion of the nanoparticles within the liquid; forming an aerosol from the dispersion; and directing the aerosol onto a substrate utilizing the aerosol to form charge-trapping centers comprising the nanoparticles, each individual charge-trapping center being spaced from other charge trapping centers by intervening gaps.
