Functional Single-Layer Graphene Sheets from Aromatic Monolayers

Self‐assembled monolayers of aromatic molecules on copper substrates can be converted into high‐quality single‐layer graphene using low‐energy electron irradiation and subsequent annealing. This two‐dimensional solid state transformation is characterized on the atomic scale and the physical and chem...

Description
Summary:Self‐assembled monolayers of aromatic molecules on copper substrates can be converted into high‐quality single‐layer graphene using low‐energy electron irradiation and subsequent annealing. This two‐dimensional solid state transformation is characterized on the atomic scale and the physical and chemical properties of the formed graphene sheets are studied by complementary microscopic and spectroscopic techniques and by electrical transport measurements. As substrates, Cu(111) single crystals and the technologically relevant polycrystalline copper foils are successfully used.
