Graphene is a single layer of carbon atoms arranged in a hexagonal lattice. It is the thinnest material known and has remarkable properties such as strength, conductivity, and transparency. Graphene was first isolated in 2004 and has potential applications in electronics, solar cells, touchscreens, and more. It could replace silicon in transistors and integrated circuits due to its high electron mobility and thermal and electrical conductivity. Graphene is seen as an important material that will change electronics and enable new technologies in the future.

14. The inventersAndre Geim and Konstantin Novoselov have shown that carbon in such a flat form has exceptional propertiesKonstantin Novoselow and Andre Geim were awarded the 2010 Nobel Prize for physics.

15. HistoryThe theory behind the substance graphene was first explored by theoretical physicist Philip Wallace in 1947.

16. In 1960’s it was believed that physically graphene cannot exist abecause of thermodynamic unstability

17. Graphene in itself however wasn't discovered until 2004 in its full observable and testable form

18. Since then, in the past 6 years, scientists have discovered that the substance retains some amazing properties.

19. Single layers of graphite were previously (starting from the 1970s) grown epitaxially on top of other materials.

20. There have also been a number of efforts to make very thin films of graphite by mechanical exfoliation

21. A key advance in the science of graphene was brought by Andre Geim and Konstantin Novoselov at Manchester University

22. Scotch tape techniqueStructure of GrapheneSheets of graphene are bonded by loose bond in graphite. These bonds are broken and sheets are isolated to form graphene. These isolated hexagonal sheets are graphene.
