Graphene is
- A. A two dimensional material consisting of a single layer of carbon atoms arranged in a honeycomb or chicken wire structure.
- B. A tube-shaped material made of carbon, having a diameter measuring on the nanometre scale.
- C. Completely non-transparent material.
- D. None of the above.
Answer: A. A two dimensional material consisting of a single layer of carbon atoms arranged in a honeycomb or chicken wire structure.
Explanation: Graphene is formally defined as a two-dimensional carbon allotrope. It consists of a single layer of carbon atoms arranged in a 2-D honeycomb lattice. Additionally, it is an extremely thin material that is both flexible and highly transparent.
