Researchers have developed the world’s thinnest metallic nanowire, which could be used to miniaturise many of the electronic components we use every day.

The researchers, from the Universities of Cambridge and Warwick, have developed a wire made from a single string of tellurium atoms, making it a true one-dimensional material. These one-dimensional wires are produced inside extremely thin carbon nanotubes (CNTs) – hollow cylinders made of carbon atoms. The finished ‘extreme nanowires’ are less than a billionth of a metre in diameter – 10,000 times thinner than a human hair.
