2-D Transistors...

Argonne National Laboratories: Link Below

The electronics world has been dreaming for half a century of the day you can roll a TV up in a tube. Last year, Samsung even unveiled a smartphone with a curved screen—but it was solid, not flexible; the technology just hasn’t caught up yet.

But scientists got one step closer last month when researchers at the U.S. Department of Energy’s Argonne National Laboratory reported the creation of the world’s thinnest flexible, see-through 2-D thin film transistors.

These transistors are just 10 atomic layers thick—that’s about how much your fingernails grow per second.

Transistors are the basis of nearly all electronics. Their two settings—on or off—dictate the 1s and 0s of computer binary language. Thin film transistors are a particular subset of these that are typically used in screens and displays. Virtually all flat-screen TVs and smartphones are made up of thin film transistors today; they form the basis of both LEDs and LCDs (liquid crystal displays).

“This could make a transparent, nearly invisible screen,” said Andreas Roelofs, a coauthor on the paper and interim director of Argonne’s Center for Nanoscale Materials. “Imagine a normal window that doubles as a screen whenever you turn it on, for example.”
