Owing to an extremely fine structure
that has a diameter measuring on the nanometer-scale (thin tube-shaped
material) and superior physical and chemical properties, the carbon
nanotube is expected to be used for various applications including
high-resolution AFM probes, flat panel displays, extremely lightweight
and high-strength materials, high performance transistors, interconnect
materials, fuel cells, ultra-sensitive sensors, absorbents and
conductive coatings. "There are only a handful of companies in each part of the
