  • Patent number: 8966411
    Abstract: This disclosure relates generally to systems and methods of providing standardized topographical configurations for template regions. In one embodiment, a set of array arrangements is selected. Arrays of template structures are then formed on at least one substrate. Each of the arrays is arranged in accordance with an array arrangement in the set of array arrangements such that the arrays correspond surjectively onto the set of array arrangements. After the arrays are formed, a self-assembly material is provided on the arrays. Self-assembly patterns formed by self-assembling material as a result of the arrays may be empirically observed and used to map a set of self-assembly pattern arrangements surjectively onto the set of array arrangements. Using this mapping, a combination of the self-assembly pattern arrangements that match a target pattern arrangement can be used to select a combination of array arrangements from the set of array arrangements for a template region.

  • Patent number: 8840954
    Abstract: Provided is a transparent carbon nanotube (CNT) electrode comprising a net-like (i.e., net-shaped) CNT thin film and a method for preparing the same. More specifically, a transparent CNT electrode comprises a transparent substrate and a net-shaped CNT thin film formed on the transparent substrate, and a method for preparing a transparent CNT electrode, comprising forming a thin film using particulate materials and CNTs, and then removing the particulate materials to form a net-shaped CNT thin film. The transparent CNT electrode exhibits excellent electrical conductivity while maintaining high light transmittance. Therefore, the transparent CNT electrode can be widely used to fabricate a variety of electronic devices, including image sensors, solar cells, liquid crystal displays, organic electroluminescence (EL) displays, and touch screen panels, that have need of electrodes possessing both light transmission properties and conductive properties.
