MICRO-AND NANO-FABRICATION OF CONNECTED AND DISCONNECTED METALLIC STRUCTURES IN THREE-DIMENSIONS USING ULTRAFAST LASER PULSES

摘要

In one aspect, a method for fabricating metal structures in two or three dimensions is disclosed, which includes providing a mixture of a polymer, a metal precursor and a solvent, and applying the mixture to a surface of a substrate. The applied mixture can then be cured (e.g., via a heat treatment) to generate a polymeric layer (e.g., a polymeric film) with ions associated with the metal precursor distributed therein. Subsequently, radiation (e.g., radiation pulses) at a wavelength to which the polymeric layer is substantially transparent is focused onto at least one location of the polymeric layer so as to cause chemical reduction of metal ions associated with the metal precursor within at least a portion of that location, thereby generating at least one metalized region.

1. A method of generating metal structures, comprising:
providing a mixture of a compound, a metal precursor, and a solvent, applying the mixture to a surface of a substrate, curing the applied mixture to generate a cured mixture, and focusing radiation onto at least one location of the cured mixture so as to form at least one metal structure within at least a portion of said location.
