Adding foreign atoms to graphene boosts its properties

Monolayer graphene finds practical applications in many fields, thanks to its desirable intrinsic properties. However, these properties can also limit its potentials. The addition of foreign atoms can help, but requires precise control. Now, researchers from South Korea invented a simple methodology to achieve fine control over the integration of foreign atoms with graphene, developing composite graphene-based heterostructures that can be used to store energy at low cost and fabricate ultrathin, wearable electronics.
