Graphene has been a wonder material ever since it was first isolated in 2004. A graphene sheet, one carbon atom thick, is strong, lightweight and highly conductive, and researchers have been ...

In a graphene sheet, each carbon atom forms bonds with ... the periodic potential of the honeycomb lattice results in a band structure in which the valence and conduction bands touch at just ...

To overcome this, a porous version of graphene, known as a graphene aerogel, can be created by separating the graphene sheets with air-filled pores. This allows the three-dimensional structure to ...

Scientists in Brazil have made the largest chemically synthesised graphene sheet ever reported. Graphene – single-atom-thick sheets of ... I’m fascinated by the myriad of different properties of these ...

Additionally, graphene also has potential to be used as photoactive material, since its bandgap and band-position can be induced and tuned via chemical functionalization or by controlling the size of ...

Whenever two sheets with a repeating pattern are ... Their study is published in Physical Review Letters. Graphene's unique ...
