Electrical Rectification … …of dibenzo[ g , p ]chrysene (DBC), considered as a small portion of graphene, was discussed by C.‐h. Chen and R.‐S. Liu et al. in their Full Paper on page 1181 ff. The framework of DBC, an all‐hydrocarbon polyaromatic compound, is twisted and the non‐planarity is illustrated by the tortoise carapace (see picture). Scanning tunneling spectroscopy (STS) of both isolated and close‐packed DBC molecules revealed diode‐like I / V behaviors. The more‐pronounced electric rectification for the latter is attributed to orbital‐mediated tunneling through the HOMO levels of ππ stacked DBC molecules.
