Sheets of bismuth, gallium, indium, tin and lead can now be made just a few atoms thick by crushing them at a high temperature and pressure between two sapphires ...

gold is usually a metal, but if single-atom-layer thick, the gold can become a semiconductor instead." Historically, attempts to create single-atom sheets of gold have been hindered due to the ...

Taking inspiration from ancient techniques, researchers have forged relatively large sheets of metal that are just atoms thick, enabling them to more readily study the weird properties of these ...
