Method for manufacturing segmented nanowires for nanowire structural element, involves forming nanowires in nanopores of template by electrochemical deposition, and disintegrating and removing template to expose nanowires

摘要

The method involves providing a template i.e. polyethylene terephthalate (PET) film (12), with multiple nanopores (32). Nanowires (34) are formed in the nanopores by electrochemical deposition of alkaline electrolyte solution with concentration of 0.01 to 0.3 mole metal species per liter. The deposition is performed with a cyclic ternary pulse sequence comprising cathodic separation pulses, electro-less pulse intervals and anodic counter pulses, where middle current density amounts to total pore surface between 1 to 40 mA/cm 2>. The template is disintegrated and removed to expose the nanowires. An independent claim is also included for a nanowire comprising multiple intermediate segments.
