Natural computing with complex atomic switch networks

Self-organizing devices can be used to overcome known scaling limits in electronic computing, resulting in networks with unique operational characteristics which may help solving complex problems. The multi-electrode array developed here consists of a silicon substrate with platinum electrodes and an atomic switch network comprised of electro-deposited self-organized silver nanowires on a grid of copper posts, thus combining bottom-up and top-down approaches. Controlling the copper seed size enabled tailoring the forms and dimensions of the silver structures.
