Controlling the growth of carbon nanotubes over large surface areas is critical to making transistors with sufficient current output and consistent properties for use in electronic circuits. The electrodes of these transistors are located at the ends of the rows of nanotubes so that thousands of nanotubes connect both electrodes, increasing the current.
In a paper published in Nature Nanotechnology, the researchers, led by John Rogers, a professor of engineering and materials science at UIUC, have shown that transistors made of around 2,000 nanotubes can carry currents of one ampere (thousands of times more possible with individual nanotubes). Researchers have also developed a technique to transfer nanotube arrays to any substrate, including silicon, plastic, and glass.
