New Chemical Material---GRAPHENE

Graphene, is a thin layer of pure carbon; it is a single, tightly packed layer of carbon atoms that are bonded together in a hexagonal honeycomb lattice. In more complex terms, it is an allotrope of carbon in the structure of a plane of sp2 bonded atoms with a molecule bond length of 0.142 nanometres. Layers of graphene stacked on top of each other form graphite, with an interplanar spacing of 0.335 nanometres. 石墨烯,是一层薄薄的纯碳;它是一个紧密的碳原子层粘合在一起,六角蜂巢晶格。在更复杂的术语中,这是碳的同素异形体的结构面sp2键合原子分子键长为0.142纳米。层石墨烯堆叠在彼此形成石墨,用一个平面间距为0.335纳米。

One of the most important properties of graphene is electron transport properties of graphene showed abnormal integer quantum hall effect. The hall conductance of quantum conductance of an odd number of times, and can be observed at room temperature [1-3]. This phenomenon can be used to prove the relativistic quantum mechanics point of view, that is to say the graphene electronic belongs to the scope of Dirac equation. 

石墨烯的一个最重要的性质是电子运输特性，石墨烯表现出了异常的整数量子霍尔效应。其霍尔电导为量子电导的奇数倍，且可以在室温观测到[1-3]。这一现象可以用来证明相对论的量子力学的观点，也就是说石墨烯的电子属于Dirac方程适用范围的电子。

Graphene is considered has extensive application prospect in terms of transistor - it electronic can not move through the scattering and the subtle distance. The feature of fast switching signal needed for manufacturing transistor is very important. The new diaphragm can substantially increase the speed of the computer. This application has been confirmed. 

    石墨烯被认为在晶体管方面具有广泛的应用前景———它里面的电子可以不通过散射而进行亚微细距离移动。这种特性对于制造需要快速转换信号的晶体管非常重要。这种新膜片可以大幅提高计算机的速度。这一应用前景目前已经被证实。
