Carbon nanotube networks: applications on flexible substrates

A method for producing large-area, low-temperature electronics on flexible substrates is developed in this paper. Randomly interconnected networks of single-walled carbon nanotubes are placed between electrodes. The carbon nanotube networks (CNN´s) are electrically conductive over macroscopic dimensions and doped to behave like n- or p-type semiconductors with a effective field effect mobility of 10 cm²/Vs and an on/off current ratio of ∼ 10⁴. The CNN´s has an application at room temperature to flexible substrates through a liquid deposition.
