Graphene --- A Miracle Material

Graphene will revolutionize the electronics industry in near future. It will totally replace silicon in near future.Graphene is versatile and promising materials ever discovered. Andre Geim and Konstantin Novoselov who discovered this was awarded Nobel Prize for Physics in 2010.Graphene is a single layer of carbon atoms which permit flow of electrons 30 times faster than they do in silicon.Its thermal conductivity is much higher than that of silver. Since graphene have high conductivity there is no need to deposit copper or aluminum wires when fabricating a semiconductor as done on silicon based semiconductor. It is more environmentally friendly than silicon ones.Since Graphene is transparent it absorbs 2.3 % of light falling on it and maintains its 2D properties at room temperature unlike silicon based semiconductors. Since Graphene is stronger and stiffer than diamond and it 200 times tougher than steel and mechanically robust.Like rubber it can be stretched by a quarter of its length.Its surface area is the largest known for its weight. Its unique flexibility will allows scientists to design computers and smartphones that can be folded into any shape. Graphene based products may be available in five years times. Graphene will revolutionize the electronics industry in near future. It will totally replace silicon in near future. Graphene will be used extensely in touch screen technology since it is cheap.Much faster computers,advanced mobile phones,radar systems will be manufactured using graphene materials.Graphene exciting new technology will change our lives in the 21st century.
