The article focuses on the single-walled carbon nanotubes (SWNTs), which are being contended to augment silicon as the semiconducting layer of the field-effect transistor. However, SWNT synthesis produces a mixture of semiconducting and metallic nanotubes, in which the metallic ones cause transistors to short. Thus, a group of researchers developed a separation technique wherein thin-film transistors are made in a single step in which semi conducting and metallic nanotubes are segregated.
