Abstract

Abstract : One of the major challenges in the practical use of nano-objects is their integration into complex structures in a controlled way. We have developed two promising techniques by which to direct the in situ growth of metallic and semiconducting nano-objects. ENDOM, or Electroless Nanowire Deposition on Micropatterned substrates, employs electroless deposition, while SENDOM, or SEmiconductor Nanowire Deposition on Micropatterned substrates, uses chemical bath deposition. In ENDOM nanowire adhesion to the substrate can be controlled using the concentration of bath additives. Using this effect we show that copper nanowires can be transferred to a variety of substrates. After transfer, the nanowires maintain their size, structural integrity, pattern and properties. Using SENDOM, we show that the nanowire formation is controlled by the interaction of a chalcogenide ion with the surface, and consequently is strongly pH dependent.
