Engineers have proposed the possibility of 'two-dimensional' metamaterials. These one-atom-thick metamaterials could be achieved by controlling the conductivity of sheets of graphene, which is a ...

Controlled layer-by-layer removal of graphene. (A) Schematic illustration of the method: (Step 1) The bilayer graphene on top of a Si/SiO2 substrate. (Step 2) A patterned layer of zinc metal is ...

Single-sheet graphene dispersion when substantially spaced apart in liquid cells or solid film matrices can exhibit novel excited state absorption mechanism that can provide highly effective broadband ...

Graphene is a material that has a one-atom layer of carbon atoms with a thickness of only 335 pm. It can be modified using oxidization and functionalization. For example, graphene gains properties ...
