Carbon nanotubes (CNTs) are currently one of the most intensively studied research subjects, because their intrinsic properties such as nanometric dimensions, high aspect ratio, good thermal and electrical conductivity, and high Young's modulus, may open up many application opportunities in advanced industries and the nanosciences 1-3. However, the future integration of CNTs with conventional microelectronics, and their use in the development of novel devices, require that CNTs be grown in highly ordered arrays, or be located at specifically defined positions, such as on pre-patterned catalysts.
