From: U-shaped relationship between current and pitch in helicene molecules
I − V behaviors of [12]helicene contacted with carbon chain electrodes.
The pitch of the relaxed (gas-phase) [12]helicene molecule is d = 3.4 Å. (a) I − V curve under different pitch d. (b) Current varies with d under the bias of 2.0 V. Inset: Conductance under zero bias on a logarithmic scale. G0 is the conductance quantum (G0 = 2e2/h).
