Researchers Optimize Light Absorption Properties of Graphene

Although graphene has various properties—for instance, it is an exceptionally good conductor—it does not have the ability to optimally absorb light. In order to overcome this constraining feature of graphene, which is otherwise an amazing material, physicists chose to embed a graphene sheet within a flat photonic crystal, which efficiently controls the flow of light.
