Single-wall carbon nanotubes (SWCNT) have found many uses in electronics and new touch screen devices. Carbon nanotubes are sheets of one atom-thick layer of graphene rolled up seamlessly into different sizes and shapes. To be able to use them in commercial products like transparent transistors for phone screens, researchers need to be able to easily test nanotubes for their materials properties, and the new method helps with this.

Professor Esko I. Kauppinen's group at Aalto has years of experience in making carbon nanotubes for electronic applications. The team's unique method uses aerosols of metal catalysts and gasses containing carbon. This aerosol-based method allows the researchers to carefully control the nanotube structure directly.
