    IBM carbon nanotubes in solution

    Date added: 2012-10-28

    IBM researcher Hongsik Park observes different solutions of carbon nanotubes. Carbon nanotubes, borne out of chemistry, have largely been laboratory curiosities as far as microelectronic applications are concerned. Carbon nanotubes naturally come as a mix of metallic and semiconducting species and need to be placed perfectly on the wafer surface to make electronic circuits. For device operation, only the semiconducting kind of tubes is useful which requires essentially complete removal of the metallic ones to prevent errors in circuits. (Credit: IBM)
