Scientists at the University of Washington have developed LEDs out of tungsten selenide that are only three atoms thick.
The story from EE Times says that conventional inorganic LEDs are much thicker than organic LEDs, which makes them not especially useful for wearable devices. And it’s not clear whether the LEDs in U of W work will have sufficient output for general use.
News of the research first appeared in the journal Nature Nanotechnology, which is behind a paywall. Similar work that’s part of the Nature issue was done at MIT and Vienna University of Technology.
