Novel method of large area graphene fabrication

Abstract

Studying of physical properties of graphene and graphene devices requires fabrication graphene samples of large area. Our fabrication method does not demand special expensive equipment and can be easily implemented. Single-layer graphene flakes with the size up to 200 μm and few-layer graphene flakes with the size up to 2000 μm were obtained by this technique. These flakes can be produced on various substrates including transparent ones. Atomically thin films of other layered materials can be also obtained using this method.
