The LED with a thickness of only 3 atoms was born

Although LED development has become very thin nowadays, R&D personnel's pursuit of this “thin” seems to be endless. A few days ago, researchers from the University of Washington announced the world's thinnest LED - the same thickness as three atoms. Xiaodong Xu, the co-author of the research report, said: "This thin, foldable LED will play a crucial role in the development of portable electronic devices."

Researchers said that the thickness of this LED is 10 to 20 times thinner than current LED, and it can fold, which will greatly increase its flexibility, and will also play a role in the future development of wearable devices. . In addition, because such LEDs are extremely thin, future researchers can use optical signals instead of the electrons currently used in certain micro computer chips to increase their operating efficiency and reduce the heat generated in the process.

However, Xu Xiaodong did not mention in the article why the LED size cannot be reduced. In addition, they hope that in the future, they will be able to find more uses for this ultra-thin LED.
