The stacking of graphene in a pseudocrystallite

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.
