QUT researchers accidentally discover atomic-scale wires Watch Now Researchers from Australia, China, and Japan are one step closer to shrinking electronic devices to molecular scale after accidentally developing a wire that is just one atom wide. The study , which was carried out by researchers from the Queensland University of Technology’s (QUT) Centre for Materials Science, Shanghai’s Fudan University, and Japan’s National Institute for Materials Science, was initially examining the properties of silver on an atomic scale. They did this by putting nanoparticles of silver on the outside of tiny nanorods that have channels inside. According to QUT professor Dmitri Golberg, these experiments are usually performed in a vacuum, but they decided to test it in regular air. “When we do this in a vacuum, or in some inert atmosphere as people usually do, nothing happens,” he said. “But we did it in air. The atoms from silver particles diffused very fast and they diffused inside the channels.” He explained that the expected result for such an experiment would be that the silver would react with oxygen in the air and form silver oxide. Instead, the atoms formed inside the channels in a “self-organisation process” like water drops going through… Read full this story
