Abstract

The diversity of carbon materials is fundamentally linked to their internal structure. However, the intrinsic attribute of the carbon structure in relation to the stacking order of graphene layers remains ambiguous. Our work focuses on the internal structure within stacked graphene layers, demonstrating the negative correlation between the (00l) interlayer spacing and the number of layers can be expressed by two simple exponential equations. Furthermore, we propose that graphene layers are generally stacked into a pseudocrystallite, in which the internal stacking order and spatial orientation codetermine the macroscopic characteristics of carbon structures. This perspective could provide a method for comprehending the stacking sequence within a layered carbon system.

石墨烯在假晶中的堆叠

碳材料的多样性从根本上与其内部结构有关。然而，碳结构的内在属性与石墨烯层的堆叠顺序之间的关系仍然不清楚。我们的工作集中在堆叠石墨烯层的内部结构上，证明层间距和层数之间的负相关关系可以用两个简单的指数方程表示。此外，我们提出石墨烯层通常堆叠成假晶，其中内部堆叠顺序和空间取向共同决定了碳结构的宏观特征。这一观点可以为理解层状碳体系内的堆积顺序提供一种方法。

期刊介绍： The journal Carbon is an international multidisciplinary forum for communicating scientific advances in the field of carbon materials. It reports new findings related to the formation, structure, properties, behaviors, and technological applications of carbons. Carbons are a broad class of ordered or disordered solid phases composed primarily of elemental carbon, including but not limited to carbon black, carbon fibers and filaments, carbon nanotubes, diamond and diamond-like carbon, fullerenes, glassy carbon, graphite, graphene, graphene-oxide, porous carbons, pyrolytic carbon, and other sp2 and non-sp2 hybridized carbon systems. Carbon is the companion title to the open access journal Carbon Trends. Relevant application areas for carbon materials include biology and medicine, catalysis, electronic, optoelectronic, spintronic, high-frequency, and photonic devices, energy storage and conversion systems, environmental applications and water treatment, smart materials and systems, and structural and thermal applications.
