Every few years, a new material with unique properties emerges and fascinates the scientific community, typical recent examples being high-temperature superconductors and carbon nanotubes. Graphene is the latest sensation with unusual properties, such as half-integer quantum Hall effect and ballistic electron transport. This two-dimensional material which is the parent of all graphitic carbon forms is strictly expected to comprise a single layer, but there is considerable interest in investigating two-layer and few-layer graphenes as well. Synthesis and characterization of graphenes pose challenges, but there has been considerable progress in the last year or so. Herein, we present the status of graphene research which includes aspects related to synthesis, characterization, structure, and properties.
每隔几年，就会有一种具有独特性质的新材料出现并吸引科学界的关注，近期典型的例子有高温超导体和碳纳米管。石墨烯是具有诸如半整数量子霍尔效应和弹道电子输运等非凡性质的最新热门材料。这种作为所有石墨碳形式母体的二维材料严格来说预期由单层组成，但对研究双层和少层石墨烯也有相当大的兴趣。石墨烯的合成与表征带来了挑战，但在过去一年左右已经取得了相当大的进展。在此，我们展示石墨烯研究的现状，其中包括与合成、表征、结构和性质相关的方面。
