Graphene's electrical properties include electrons so mobile they travel at near light speed. But without a bandgap, graphene's promise for electronics and photonics can't be realized. Now researchers can precisely tune a bandgap in bilayer graphene from zero to 0.25 eV, in the infrared energy region.
