Patterning technique for gold nanoparticles on substrates using a focused electron beam

Beilstein Journal of Nanotechnology, 2015
We propose a novel patterning technique for gold nanoparticles on substrates that combines a chemical reaction with electron beam irradiation. First, gold nanoparticles are placed in a two-dimensional arrangement on the substrate.
