Single-walled carbon nanotubes (SWCNTs) are cylindrical structures made of a single layer of carbon atoms arranged in a hexagonal lattice. They are incredibly strong and lightweight, with remarkable electrical and thermal conductivity. Due to their unique properties, SWCNTs have potential applications in various fields, including electronics, materials science, and nanotechnology. These nanotubes can be produced through methods like chemical vapor deposition and arc discharge. Their small diameter, typically around one nanometer, allows them to exhibit unique quantum properties, making them valuable for research in nanotechnology and materials science.
