Understanding motions of thin layers may help design solar cells, flexible electronics and catalysts of the future. New research shows how individual atoms move in trillionths of a second to form wrinkles on a 3-atom-thick material. It was made possible with SLAC’s instrument for ultrafast electron diffraction (UED), which uses energetic electrons to take snapshots of atoms and molecules on timescales as fast as 100 quadrillionths of a second.
Monolayers, or 2D materials, contain just a single layer of molecules. In this form they can take on new and exciting properties such as superior mechanical strength and an extraordinary ability to conduct electricity and heat...
