Researchers develop world's thinnest 1D metallic nanowire
UK-based researchers have developed a wire made from a string of tellurium atoms, making the 1D material the world's thinnest metallic nanowire. The wires, 10,000 times thinner than a human hair, were made using hollow cylinders made of carbon atoms. Tellurium, which normally behaves like a semiconductor, acts as a metal when injected into carbon nanotubes and confined to 1D.
