Take a material that is a focus of interest in the quest for
advanced solar cells. Discover a "freshman chemistry level" technique
for growing that material into high-efficiency, ultra-small lasers. The result,
disclosed today (Monday, April 13) in Nature Materials, is a shortcut to lasers
that are extremely efficient and able to create many colors of light.
That makes these tiny lasers suitable for miniature
optoelectronics, computers and sensors.
