Corannulene is a hydrocarbon molecule (C₂₀H₁₀) with a bowl-shaped three-dimensional structure. This molecular shape features a characteristic known as the Bowl inversion, where the front and back are reversed. We have previously confirmed resistance change phenomena by fabricating layered structures based on prior research using simulations based on density functional theory with smanen (C₂₁H₁₂), another bowl-shaped molecule. During these observations, we hypothesized that the mechanism behind the resistance change phenomenon stems from the unique shape of the Sumanene molecule. Therefore, in this study, we fabricated a structure using a corannulene molecule instead of Sumanene and performed J-V (current density-voltage) measurements. This experiment aims to experimentally clarify whether the resistance change in the graphene/Sumanene/graphene structure is attributable to the bowl-shaped molecule.
