NOVELTY - Method for manufacturing electrode on substrate involves: generating solution including composite (860) having nanotubes and conjugated polymer, where conjugated polymer is used to disperse nanotubes in solution, and nanotubes constitute majority of composite by weight; and coating solution onto substrate to form electrode including network of carbon nanotubes from composite.    USE - For manufacturing electrode on substrate using carbon nanotubes, such as transparent electrode; and manufacturing semiconductor device having carbon nanotube-based electrode regions (claimed). The electrode is used in a variety of applications including circuitry (electrodes/interconnects), batteries, semitransparent/transparent devices or conducting materials (transparent electrodes) useful for touch screens, solar cells, and flat panel displays; and supercapacitors.    ADVANTAGE - The method provides improved method for manufacturing electrode using nanotubes, such as carbon nanotubes. In the prior art, although some electrodes use carbon nanotubes or carbon nanotube (CNT) network; such networks can experience problems relating to relatively large inter-tube junction resistance, especially between metallic and semiconducting tubes. Another such problem relates to deposition of CNT networks, which has been challenging to implement due to inhomogeneous, inefficiently networked films. In addition, applicable methods of deposition may require use of large amount of surfactant that needs to be removed, can limit size of films to size of membrane filter, and may involve undesirable transfer printing step. Such electrodes can be difficult to implement as transparent electrodes. In the improved method solution including nanotubes and conjugated polymer is generated, in which nanotubes constitute at least 50 wt.% of non-solvent portion of solution. The using of conjugated polymer to disperse nanotubes in solution includes n-stacking conjugated polymer on nanotubes to prevent aggregation of nanotubes into intertwined bundles of nanotubes having diameter greater than 100 nm. Thus conjugated polymer is used to disperse nanotubes in solution, and network of carbon nanotubes is formed from solution on electrode regions, including nanotube bundles having cross-section of less than 40-100 nm.    DETAILED DESCRIPTION - Method for manufacturing electrode on substrate involves: generating solution including composite (860) having nanotubes and conjugated polymer, where conjugated polymer is used to disperse nanotubes in solution, and nanotubes constitute majority of composite by weight; and coating solution onto substrate to form electrode including network of carbon nanotubes from composite. The step of generating solution includes selecting bundle size for carbon nanotubes in carbon nanotube network based upon transmittance and conductance values for electrode, and setting concentration of conjugated polymer in composite based upon selected bundle size; selecting density for carbon nanotubes in carbon nanotube network, and setting at least one of solution volume and concentration of conjugated polymer in composite, based upon selected density; selecting density and bundle size for carbon nanotubes in carbon nanotube network, and setting concentration of conjugated polymer in composite based upon the selected density and bundle size; or selecting density and bundle size for carbon nanotubes in carbon nanotube network based upon transmittance value for carbon nanotube network, setting concentration of conjugated polymer in composite based upon selected density and bundle size, and using conjugated polymer to disperse nanotubes to set transmittance of carbon nanotube network. The method further involves treating carbon nanotube network to dope carbon nanotube network and remove at least some of conjugated polymer from carbon nanotube network; and doping polymer to increase conductivity of polymer. The step of generating solution includes generating composite solute in which carbon nanotubes constitute at least 50 wt.% of solute.
