C NTs Structure and Features
C nanotubes are cylindrical molecules formed from rolled-up sheets of graphite. Their composition can be categorized into two main kinds: single-walled NTs (SWNTs), which consist of a single layer, and multi-walled NTs (MWNTs), comprised of multiple concentric cylinders. The chirality, related describes the angle at which the graphite sheet is rolled, dictates the tube’s electrical characteristics. Based on the chirality, SWNTs can be metallic or semiconducting. Moreover, their exceptional physical strength, remarkable heat conductivity, and high electrical conductivity make them highly valuable for a extensive range of applications, including materials, electronics, and sensors. The aspect ratio – the ratio of length to diameter – is also crucial in influencing the behavior.
