Abstract: PURPOSE: A graphene crystal structure analytical method is provided to simply analyze the marginal structure and grating orientation of graphene without using expensive equipment. CONSTITUTION: A graphene crystal structure analytical method is as follows. A graphene sample is placed on a substrate. A substrate with an orientation screen is layered on the substrate with a fixed space from the substrate, and a crystal cell is made by injecting a crystal material into the space. The director of the liquid crystal and correlation of the graphene grid direction is set up. The correlation between the director of the liquid crystal and the grating orientation of graphene is set up. The director of the liquid crystal is determined after observing the texture of the crystal cell, and the marginal structure and grating orientation of graphene is determined based on the director of the liquid crystal.
