The University of Manchester scientists, who discovered graphene in 2004, have reported their findings about bilayer graphene’s electronic properties in the Science journal.
The researchers Kostya Novoselov and Andre Geim in partnership with other scientists at the universities of Moscow, Nijmegen and Lancaster have investigated in detail about the impact of interactions between electrons in bilayer graphene on its electronic properties.

The researchers utilized superior quality bilayer graphene instruments that were fabricated by suspending graphene sheets in vacuum. This method could remove majority of unnecessary scattering processes for electrons in graphene, thus improving its electron-electron interaction effect.
A unique two-dimensional material, graphene can be spotted as a single layer of carbon atoms organized in a hexagonal lattice. The binding of two graphene layers in a specific manner forms the innovative material, bilayer graphene.
Both bilayer graphene and graphene demonstrate very high mechanical strength as well as thermal and electron conductivities ascribed to excellent quality of crystals and high electron velocity. Geim stated that superior quality bilayer graphene is an innovative material. Novoselov commented that graphene production technology advances everyday, which has an instant impact on the viability and range of prospective applications.
Since graphene has different quasiparticles when compared to other metals, its electronic properties are unique. It has chiral symmetry between its holes and electrons. This symmetry exists between antiparticles and particles in high-energy physics. With these properties, graphene is at times termed as 'CERN on a desk', which refers to the Large Hadron Collider located in Switzerland.
