  Centimeter scale aligned carbon nanotube arrays are grown from nanoparticle
metal catalyst pads. We find the nanotubes grow both with and against the wind.
A metal underlayer provides in-situ electrical contact to these long nanotubes
with no post growth processing needed. Using the electrically contacted
nanotubes, we study electrical transport of 0.4 cm long nanotubes. The source
drain I-V curves are quantitatively described by a classical, diffusive model.
Our measurements show that the outstanding transport properties of nanotubes
can be extended to the cm scale and open the door to large scale integrated
nanotube circuits with macroscopic dimensions.
