Formation of precise 2D Au particle arrays on prepatterned substrates

Published on March 8, 2012

The fabrication process of precise 2D Au nanoparticle arrays is presented in this video. The technique is based on the dewetting of Au films on prepatterned substrates. All individual processing steps are presented, from patterning of the substrate by nanoimprint lithography, to deposition of a thin gold film and dewetting, through to the final analysis.
