Nanonets: Wet assembly of Nanowires

OBJECTIVES
To exploit the functionalities of nanowires through collective use within nanonets.

Highlight

Based on a simple and versatile fabrication method, the collective use and integration of high aspect ratio nanostructures, such as carbon nanotubes and Si or ZnO nanowires (NWs), leads to nano-size networks (nanonets).
The nanonets address multiple application fields, including transparent conducting material, light detection, active material for bio-sensing devices, or materials with interesting wettability properties.
In particular, by combining sol-gel protocols and hydrothermal synthesis, well controlled ZnO NWs are grown for further integration in nanonets.
