Nanowires that are only three atoms in width have been developed by a doctoral student at Vanderbilt University, working with Oak Ridge National Laboratory. Junhao Lin employed transition-metal dichalcogenides, a semiconductor material, in creating the tiny nanowires, which may lead to a flexible electronics film to be used in mobile devices. "You could potentially have screens or pages that are flexible like a sheet of paper. You might be able to fold them and then open them up to see the screen. The material is flexible already because it's just one layer of atoms," Vanderbilt's Sokrates Pantelides said.
