sciencehabit writes "Researchers have created the world's thinnest pane of glass. The glass, made of silicon and oxygen, formed accidentally when the scientists were making graphene, an atom-thick sheet of carbon, on copper-covered quartz. They believe an air leak caused the copper to react with the quartz, which is also made of silicon and oxygen, producing a glass layer with the graphene. The glass is a mere three atoms thick — the minimum thickness of silica glass—which makes it two-dimensional. The team notes that the structure 'strikingly resembles' a diagram drawn by a glass theorist attempting to unravel its structure back in 1932. Such ultra-thin glass could be used in semiconductor or graphene transistors." See Nano Letters for an abstract (and another picture) to the paywalled article.
