CPC刊发了有关石墨烯的最新综述:石墨烯纳米带合成的最新进展及挑战。
制备均一的高质量的石墨烯纳米带是当今石墨烯领域乃至纳米器件领域的一大研究热点。纳米化的石墨烯由于受边缘集团的影响,会产生特征的带隙,形成窄带隙半导体,从而在纳米器件方面发挥作用。本文综述了石墨烯纳米带合成的现状,进展和面临的挑战,值得研究相关领域的朋友一看。
Graphene, the thinnest two-dimensional material in nature,
has abundant distinctive properties, such as ultrahigh carrier
mobility, superior thermal conductivity, very high surface-tovolume
ratio, anomalous quantum Hall effect, and so on. Laterally
confined, thin, and long strips of graphene, namely, graphene
nanoribbons (GNRs), can open the bandgap in the
semimetal and give it the potential to replace silicon in future
electronics. Great efforts are devoted to achieving high-quality
GNRs with narrow widths and smooth edges. This minireview
reports the latest progress in experimental and theoretical
studies on GNR synthesis. Different methods of GNR synthesis—
unzipping of carbon nanotubes (CNTs), cutting of graphene,
and the direct synthesis of GNRs—are discussed, and
their advantages and disadvantages are compared in detail.
Current challenges and the prospects in this rapidly developing
field are also addressed.
