Researchers at the University of Washington have built what they say are the thinnest-possible LEDs — tiny lights that measure just three atoms thick. Such thin and foldable LEDs are critical for future portable and integrated electronic devices, Xiaodong Xu, co-author of a paper on the research that was published over the weekend in Nature Nanotechnology, says in a statement. At three atoms thick, the researchers LEDs are said to be 10 to 20 times thinner than conventional LEDs, opening up a number of potential new uses for them.
