Nanocircuits: Fabrication of a 3D Nanoscale Crossbar Circuit by Nanotransfer‐Printing Lithography (Small 15/2010)

The cover picture shows the structure and a scanning electron microscopy image of a 3D nanoscale crossbar circuit fabricated by nanotransfer printing lithography. An array of parallel Au nanowires of 100 nm width and 100 nm spacing are printed onto an electrically switchable polymer layer, and the printing process can be repeated to fabricate a 3D circuit with multiple layers of the polymers and nanowires aligned along different directions. The conductance of the polymer sandwiched between each pair of nanowires can be modified by applying voltage biases on the nanowires. The 3D architectures can significantly increase the device density and complexity in electronic circuits, generate photonic crystals or plasmonic structures with novel optical properties, and mimic 3D neural networks with field configurable plasticity.
