Dr. Andrei Varykhalov and his colleagues in the group of Prof. Dr. Oliver Rader investigated at BESSY II the electronic properties of nickel coated with graphene and achieved an astonishing result. They could show that the conduction electrons of the graphene behave rather as light than as particles. Physicists had originally expected such behavior only for freestanding graphene layers which show a perfect honeycomb structure and not for graphene on nickel which disturbs the perfect hexagonal symmetry. Their results are supported by calculations of two theoretical groups using novel concepts. Their report was published yesterday evening in the open access journal, Phys. Rev. X, the new top...
