Eindhoven Researchers Present Revolutionary Light-Emitting Silicon (IMAGE) Eindhoven University of Technology Caption A look inside the Metal Organic Vapor Phase Epitaxy (MOVPE). This machine was used to grow 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. Credit Nando Harmsen, TU/e Usage Restrictions Credit the photographer.
