ABSTRACT
Synthesis of carbon nanotubes by chemical vapor deposition over
patterned catalyst arrays leads to nanotubes grown from specific
sites on surfaces. The growth directions of the nanotubes can be
controlled by van der Waals self-assembly forces and applied
electric fields. The patterned growth approach is feasible with
discrete catalytic nanoparticles and scalable on large wafers for
massive arrays of novel nanowires. Controlled synthesis of nano-
tubes opens up exciting opportunities in nanoscience and nano-
technology, including electrical, mechanical, and electromechanical
properties and devices, chemical functionalization, surface chem-
istry and photochemistry, molecular sensors, and interfacing with
soft biological systems.
Introduction
Carbon nanotubes represent one of the best examples of
novel nanostructures derived by bottom-up chemical
synthesis approaches. Nanotubes have the simplest chemi-
position and atomic bonding configuration but
exhibit perhaps the most extreme diversity and richness
among nanomaterials in structures and structure-prop-
