Graphene: Study

Researchers recently discovered a strange new state of matter in the dynamics of currents flowing through layers of graphene.

  • It is an allotrope of carbon, along with diamond and graphite.
  • It is a two-dimensional material consisting of a single layer of carbon atoms arranged in a honeycomb structure.
  • The stacked form of graphene is graphite.
  • Graphene was first isolated in 2004.
  • Since then, it has utilised in various innovative applications, from sensors and electronics to energy storage and healthcare.
  • Graphene is the world’s thinnest material – it is only one atom thick, one million times thinner than a human hair.
  • It is 200 times stronger than steel but six times lighter.
  • It is extremely flexible and stretchable.
  • It is an excellent electrical and thermal conductor.
  • It is almost perfectly transparent since it only absorbs 2% of light.
  • It is impermeable to gases, even those as light as hydrogen or helium.
