DENVER — Phosphorus has joined carbon as the only elements to be separated into sheets each a single atom thick, researchers announced March 7 at a meeting of the American Physical Society. The newly fabricated ultrathin material, dubbed phosphorene, could prove superior to its popular carbon counterpart for use in next-generation electronics.

Graphene, which consists of a flat honeycomb lattice of carbon atoms, has been the darling of materials scientists since 2004. That’s when Andre Geim an...
