  • Carbon nanotube synthesis for nanopore devices
    Patent number: 8470408
    Abstract: In a process for fabricating a nanopore device, at least one carbon nanotube catalyst region is formed on a structure. A plurality of nanopores is formed in the structure at a distance from the catalyst region that is no greater than about an expected length for a carbon nanotube synthesized from the catalyst region. Then at least one carbon nanotube is synthesized from the catalyst region. This fabrication sequence enables the in situ synthesis of carbon nanotubes at the site of nanopores, whereby one or more nanotubes articulate one or more nanopores without requiring manual positioning of the nanotubes.
    Type: Grant
    Filed: October 2, 2008
    Date of Patent: June 25, 2013
    Assignee: President and Fellows of Harvard College
    Inventors: Daniel Branton, Jene A. Golovchenko, Slaven Garaj, Dimitar M. Vlassarev, El-Hadi S. Sadki
