21. F of the contacts and the molecular level closest to it. Single electron tunneling effects such as Coulomb blockade are unlikely to be present here due to the strong chemisorption of the molecule to Au(111), which results in charging energies (0.7 eV for a sphere of 2 nm) ≈ energy level broadening due to contacts (0.2 eV, Ref. 15).
