文摘

We developed means to form multilayer superstructures of large collections of single-walled carbon nanotubes (SWNTs) configured in horizontallyaligned arrays, random networks, and complex geometries of arrays and networks on a wide range of substrates. The approach involvesguided growth of SWNTs on crystalline and amorphous substrates followed by sequential, multiple step transfer of the resulting collectionsof tubes to target substrates, such as high-k thin dielectrics on silicon wafers, transparent plates of glass, cylindrical tubes and other curvedsurfaces, and thin, flexible sheets of plastic. Electrical measurements on dense, bilayer superstructures, including crossbars, random networks,and aligned arrays on networks of SWNTs reveal some important characteristics of representative systems. These and other layouts of SWNTsmight find applications not only in electronics but also in areas such as optoelectronics, sensors, nanomechanical systems, and microfluidics.
