The first on-chip, visible-light source that uses “wonder material” graphene as a filament has been created by an international team of researchers. The team found that small strips of freely suspended graphene, attached to metal electrodes, can reach temperatures of up to 2800 K, allowing it to emit visible light. The research, while preliminary, opens up intriguing scientific questions, and possible applications of atomically thin, transparent, flexible displays and optical interconnects with electronic circuits……
