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.

Application of Graphene in electronics
1. PAPER PRESENTATION ON Application Of Graphene In Modern Electronics Presented By- ChinmayChepurwar G.H Raisoni College Of Engineering (An Autonomous Institute under UGC act 1956,affilated to RTMNU, Nagpur) Department of Electronics Engineering
14. The inventers Andre Geim and Konstantin Novoselov have shown that carbon in such a flat form has exceptional properties Konstantin Novoselow and Andre Geim were awarded the 2010 Nobel Prize for physics.

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
37. electrical conductivity of sheets are 10 times that of copper.

39. Thermal properties The near-room temperature thermal conductivity of graphene was recently measured to be between (4.84±0.44) ×103 to (5.30±0.48) ×103 Wm−1K−1. Mechanical properties As of 2009, graphene appears to be one of the strongest materials ever tested. 200 times greater than steel Bulk strength is 130GPa Graphene sheets, held together by van der Waals forces
47. It's essentially the basic building block for graphitic materials of all other dimensionalities; it's a stepping stone to building bigger things Fullerenes Nanotubes Sheets
71. Due to its high electronic quality, graphene has also attracted the interest of technologists who see it as a way of constructing ballistic transistors. Graphene exhibits a pronounced response to perpendicular external electric fields, allowing one to build FETs.
84. Nanogapsin graphene sheets may potentially provide a new technique for rapid DNA sequencing.Escherichia coli

86. In the future, satellites, airplanes, and cars could be manufactured out of the new composite materials. The fastest growing problem facing chip engineers today can be solved
