Carbon Nanotubes
Cylindrical nanostructures composed of rolled-up single-layer graphene sheets possessing exceptional mechanical strength and electrical conductivity.
Governing formula
Chiral Vector C_h = n a₁ + m a₂
SI unit
nm (Nanotube Diameter)
In depth
Classified as Single-Walled (SWCNT) or Multi-Walled (MWCNT). Depending on chiral indices (n, m), carbon nanotubes behave as metallic conductors or high-mobility semiconductors, with tensile strength exceeding 50 GPa.
Examples in the real world
Carbon nanotube field-effect transistors (CNT-FETs) and high-strength lightweight composite materials.
