Kostya Novoselov and Andre Geim, the University of Manchester Nobel Prize awardees, who discovered graphene in 2004, have reported in detail about bilayer graphene’s electronic properties in the Science journal.
The researchers in partnership with other scientists at the Universities of Moscow, Nijmegen and Lancaster have investigated in detail 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 the unnecessary scattering methods of electrons in graphene, thus improving the electron to electron interaction effect.
Since graphene has different quasiparticles when compared to other metals, its electronic properties are unique. It has chiral symmetry, which is a symmetry between holes and electrons, similar to that which 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.
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 that can be ascribed to excellent quality of the crystals and high electron velocities. Geim stated that superior quality bilayer graphene is an innovative material and has a specific range of applications. Novoselov commented that graphene production technology advances everyday, which has an instant impact on its viability and range of its prospective applications.
