Title: Scientists Build Thinnest-Possible LEDs To Be Stronger, More Energy Efficient
text: Most modern electronics, from flat-screen TVs and smartphones to wearable technologies and computer monitors, use tiny light-emitting diodes, or LEDs. These LEDs are based on semiconductors that emit light with the movement of electrons. As devices get smaller and faster, there is more demand for semiconductors that are tinier, stronger and more energy efficient.
