Single-walled carbon nanotubes (SWCNTs) are cylindrical structures made of a single layer of carbon atoms arranged in a hexagonal lattice. They are typically just one nanometer in diameter and can be several micrometers long. Due to their unique structure, SWCNTs exhibit remarkable electrical, thermal, and mechanical properties, making them valuable in various applications, including electronics, materials science, and nanotechnology. These nanotubes can be produced through methods like chemical vapor deposition and arc discharge. Their exceptional strength and conductivity have led to research in fields such as nanoelectronics, composite materials, and energy storage, highlighting their potential in advancing technology and materials.
