One possibility is to include carbon nanotubes in widely used electronic components, such as field-effect transistors. These single-atom-thick tubes are expected to make transistors more energy efficient compared to more run-of-the-mill silicon-based versions.In principle, the ultra-small size of the nanotubes should also help reduce the effects that radiation would have when striking memory ...
