  With the objective of integrating single clean, as-grown carbon nanotubes
into complex circuits, we have developed a technique to grow nanotubes directly
on commercially available quartz tuning forks using a high temperature CVD
process. Multiple straight and aligned nanotubes bridge the >100um gap between
the two tips. The nanotubes are then lowered onto contact electrodes,
electronically characterized in situ, and subsequently cut loose from the
tuning fork using a high current. First quantum transport measurements of the
resulting devices at cryogenic temperatures display Coulomb blockade
characteristics.
