Atomic Break Dancing in the World’s Thinnest Glass

Electron microscopy reveals the fundamental steps of bending

An international team of Cornell researchers and collaborators was recently entered into the Guinness Book of World Records for fabricating the world’s thinnest pane of glass — only two atoms thick!

Now, the team has used an electron microscope to watch individual atoms while they bend, deform and melt the glass. By tracking the atoms’ motions as they wiggle and jiggle around, the scientists identified the basic atomic “dance moves” that allow the glass to deform before it breaks. While watching the glass melt and resolidify, the researchers saw the atoms come back together in different patterns from their original arrangements — the glass retained no memory of its original structure. Now that these atomic motions can be imaged, it opens new grounds for modeling and understanding structure and properties of glasses at the most fundamental level.

The glass was discovered accidentally, and the researchers are now working on a recipe for growing large quantities of the glass, as its properties are well suited to use in computer chips and quick-charging batteries.
