Nanotube have three topology arrangements: armchair, zigzag, and Chiral. Nanotubes are elastic and strong. Nanotubes conduct heat and cold very well. A nanotube can be either metallic or semiconducting. A nanotube is metallic I the energy level that allows delocalized electrons t flow between atoms throughout the nanotube is right above the energy level used by electrons attached. A nanotube is semiconducting if the energy level of the conduction band is high enough sou that there is an energy gap between it and the valence band. Nanotubes will provide more efficient energy transmission and faster and more power computers. Nanotube tensile strength (GPa)=200, Young's modulus(GPa)=1000, and density=2.[Learn More ...]
