Nanostructure Films
A nanostructure film, comprising at least one interconnected network of nanostructures, wherein the nanostructure film is optically transparent and electrically conductive. A method for improving the optoelectronic properties of a nanostructure film, comprising: forming a nanostructure film having a thickness that, if uniform, would result in a first optical transparency and a first sheet resistance that are lower than desired; and patterning holes in the nanostructure film, such that a desired higher second optical transparency and a second sheet resistance are achieved. A method for depositing a nanostructure film on a rigid substrate comprises: depositing the nanostructure film on a flexible substrate; and transferring the nanostructure film from the flexible substrate to a rigid substrate, wherein the flexible substrate comprises at least one of a release liner and a heat- or chemical-sensitive adhesive layer.
