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

IV. 2016-10-12 The carbon nanotube (CNT) represents one of the most unique inventions in the field of nanotechnology. CNTs have been studied closely over the last two decades by many researchers around the world 2014-10-18 Consequently, all the electronic, optical, electrochemical and mechanical properties of the carbon nanotubes are extremely anisotropic (directionally dependent) and tunable. Applications of carbon nanotubes in optics and photonics are still less developed than in other fields. 2019-01-23 1998-07-01 The modern nanotube can be thought of as the ultimate fiber formed of perfectly closed, seamless shells having unique features, such as mechanical and electronic properties that are very sensitive to its geometry and its dimensions. The nanotube has many uses: Properties of Carbon Nanotubes Physical – Carbon nanotubes are inherently stronger than other modern materials, giving it extreme stiffness and strength.
