Carbon nanotube growth for GHz devices

Horizontally oriented single walled carbon nanotubes are grown with CVD between lithographically defined catalyst sites. Single walled carbon nanotubes up to 60 /spl mu/m in length are grown using methane as the feedstock. The nanoparticle catalyst is deposited from a newly developed aqueous solution requiring only photoresist and optical lithography. Carbon nanotube Y-junctions are also observed and characterized.
