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.
