Thin-Film Transistors and Circuits Based on Carbon Nanotubes

Carbon nanotubes are actively studied for thin-film transistor and electronics applications. Although these nanomaterials were first considered as potential candidates for the replacement of Si MOS type transistors in VLSI circuits, their main field of application is shifting towards large area electronics on flexible, plastic-type substrates, a domain which is at present, less demanding in terms of device dimensions and integration density. In particular, random networks of carbon nanotubes, which can be obtained by solution-processing or grown at low temperature, represent an attractive and viable option for the fabrication of electronic circuitry on non-refractory substrates. This paper briefly reviews some recent advances in the field, highlighting realisations beyond the fabrication of simple transistors.
