Figure 5: Parameters of the graphene wrinkles studied in this work.
From: Strain and curvature induced evolution of electronic band structures in twisted graphene bilayer

The parameters, l and h, of both the graphene monolayer wrinkles (blue circles) and graphene bilayer wrinkles (red circles) studied in our experiment. The filled circle represents the wrinkles showing LLs and the open circles are denoted by the wrinkles that do not show any evidence of the LL. The red dashed curve is plotted according to h2/la=1.
