(Moscow Institute of Physics and Technology) Superinjection, the effect used in lasers and LEDs creation can work in ‘pure’ semiconductors, which was previously considered impossible. This opens up new prospects for designing highly efficient blue, violet, ultraviolet, and white LEDs, as well as light sources for optical wireless communication (Li-Fi), new types of lasers, transmitters for the quantum internet, and optical devices for early disease diagnostics.
