Nanoscale LED Bypasses Efficiency Droop to Take on Laser Qualities

Using microscopic LEDs in a laboratory setting, a team of researchers including scientists from the National Institute of Standards and Technology (NIST) has increased the brightness of laser light, as well as the ability to manufacture it in a controlled environment. The newly conceived and demonstrated design may hold value for scientists overcoming limitations involving the light source’s efficiency, enhancing brightness 100× to 1000× over conventional, submicron-size LEDs. The architecture could support work spanning both large-scale and miniaturized applications. While the materials the team used in its design do not vary from those used in conventional LEDs, there is a significant difference in physical shape....
