1·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。
2·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。
3·However, unlike the semiconductor silicon, graphene has no gap between its valence and conduction bands.
然而，与半导体硅不同，石墨烯的价带和导带之间没有带隙。
4·A team of materials scientists and physicists has claimed that graphene has the potential to replace carbon fibres in the composites that are used to build aircraft.
一个由材料科学家和物理学家组成的研究小组宣称，石墨烯具有取代制造飞机的复合材料中的碳纤维的潜力。
5·Since its discovery less than a decade ago, researchers have learned that graphene conducts heat and electricity extremely well.
它问世不到十年，研究者就发现石墨烯有极其良好的导热和导电性能。
