Scientists at Lehigh University used a laser to make ordered single crystals on a disordered glass surface. In the colorized scanning electron micrograph, the green color letters represent single crystals embedded in glass shown in blue. The width of the single crystal lines is about five micrometers—about the same width as a single strand of silk from a spider’s web.
