The World's Thinnest LED: Thickness of 3 Atoms!

Recently, researchers from Washington University declare that the world's thinnest LED is only equivalent to the thickness of 3 atoms. The co-author of the study report, Xiaodong Xu said , "Foldable LED in such thinness would be crucial to the research on portable electronic devices."

The researchers indicated that the thickness of such kind of LED is 10 to 20 times thinner than that of today's LED. Besides, it's foldable, which will greatly enhance its flexibility. These two features together will play a catalytic part in development of wearable devices in the future. In addition, researchers will be able to replace electronic with optical signal on microcomputer chip by the use of this LED, thereby increasing the operating capacity while decreasing the heat generated during this process.
