Influence of graphene stacks on the structure and conductivity of shungite carbon

Abstract The influence of graphene stacks on the formation of structural and electrical parameters of shungite carbon was determined. The spatial distribution map of graphene layers and stacks consisting of these layers was obtained by the STEM method. Statistical analysis of images of graphene stacks and the gaps between them was performed. Based on the data obtained, a simplified regular structure model is proposed, within the framework that allows one to quantitatively estimate the spatial dimensions of the carbon regions and describe the integral conductivity of shungite carbon.
