State-of-the-art photocathodes grown on atomically thin layers of graphene

Researchers developed a unique approach that decouples two competing physical mechanisms that have prevented scientists from improving cold cathode efficiency.

The grey spheres represent carbon atoms in the graphene, which protects the photocathode from gases in the environment.
