Eindhoven Researchers Present Revolutionary Light-Emitting Silicon (IMAGE) Eindhoven University of Technology Caption Shared first author Elham Fadaly, is operating the Metal Organic Vapor Phase Epitaxy (MOVPE). This machine grows the nanowires with hexagonal silicon-germanium shells. The emission from this hexagonal-SiGe alloy showed to be very efficient and suitable to start producing an all-silicon laser.
