Graphene is a flat sheet of carbon just one atom thick—with the carbon atoms arranged in a honeycomb lattice.

石墨烯是一种只有单原子厚度的碳原子平面层——碳原子按蜂窝状晶格排列。

First produced in a lab back in 2004, graphene is essentially a single layer of pure carbon atoms bonded together in a honeycomb lattice so thin it's actually considered two-dimensional.

石墨烯最早在2004年诞生于一个实验室，本质上是一层由纯碳原子组成的蜂窝状晶格层，薄到竟被认为是二维物质。
