Nascent Graphene Institute Makes Steps Toward Transistors 22

judgecorp writes "A research team at Manchester has taken a big step toward building transistors with graphene. So far graphene's marvelous conductivity has actually proved a drawback, but the team has sandwiched a layer of molybdenum disulfide between layers of graphene to provide a high on/off ratio. Also, the British Government is finding £50 million to fund Manchester as a center for graphene study and development, led by two professors there, Sir Kostya Novoselov and Sir Andre Geim, who shared the 2010 Nobel prize for Physics for their work on graphene."

    "Researchers have created the world's thinnest pane of glass—and it looks oddly familiar. 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. [...] In addition to demonstrating how graphene makes it possible to produce previously unfeasible 2D-materials, ultra-thin glass could be used in semiconductor or graphene transistors."

    How about three atoms thick glass as an insulator between graphene layers?
