Publication number: 20120171106Abstract: A system and method for growing nanotubes out of carbon and other materials using CVD uses a catalytic transmembrane to separate a feedstock chamber from a growth chamber and provide catalytic material with separate catalytic surfaces to absorb carbon atoms from the feedstock chamber and to grow carbon nanotubes in the growth chamber. The catalytic transmembrane provides for greater flexibility to independently control both the gas environment and pressure in the chambers to optimize absorption and carbon growth and to provide instrumentation in the growth chamber for in-situ control of defects or observation of the carbon nanotube growth.Type: ApplicationFiled: January 4, 2008Publication date: July 5, 2012Inventors: Delmar L. Barker, W. Howard Poisl, Brian J. Zelinski, Jon N. Leonard
