Abstract
Composite transparent conductors are described, which comprise a primary conductive medium based on metal nanowires and a secondary conductive medium based on a continuous conductive film.
Claims30
A composite transparent conductor comprising:
- a primary conductive medium including a plurality of nanostructures, the nanostructures being metal nanowires or metal nanotubes;
- and
- a secondary conductive medium coupled to the primary conductive medium, the secondary conductive medium including a metal oxide film, wherein the plurality of nanostructures are below an electrical percolation threshold.
A device comprising a composite transparent conductor including:
- a primary conductive medium including a plurality of metal nanowires or a plurality of metal nanotubes;
- and
- a secondary conductive medium coupled to the primary conductive medium, the secondary conductive medium being a metal oxide film, wherein the plurality of metal nanowires or metal nanotubes are below an electrical percolation threshold.
A device comprising:
- a liquid crystal display cell including:
- a first electrode;
- and
- a second electrode, wherein a vertical distance between the first electrode and the second electrode defines a cell gap;
- wherein the first electrode is a composite transparent conductor including a primary conductive medium and a secondary conductive medium, and wherein, the primary conductive medium includes metal nanowires or metal nanotubes that have a mesh size on the order of the cell gap;
- and wherein, the secondary conductive medium is a continuous conductive film or a conductive network of nanostructures having a mesh size of about ⅕ to 1/100 of the cell gap.
