  • Method for growing carbon nanotubes
    Patent number: 9559308
    Abstract: A method of forming carbon nanotubes (CNTs) is disclosed. The method includes dispersing a plurality of substantially semiconductor pure carbon nanotube (CNT) seeds on a substrate to provide a seeded substrate, ozonating the seeded substrate to remove defects on end faces of the plurality of substantially semiconductor pure CNT seeds, and growing carbon extensions on the end faces of the plurality of substantially semiconductor pure CNTs seeds to form a plurality of substantially pure CNTs.
    Type: Grant
    Filed: July 15, 2015
    Date of Patent: January 31, 2017
    Assignee: Northrop Grumman Systems Corporation
