In charge : The energy‐level alignment and change to the surface work function (Δ φ , see picture) are measured for 4,4′‐bis(phenylethynyl)benzeneisocyanide monolayers chemisorbed on metalsurfaces. Tunneling‐barrier heights areextracted from current–voltage measurements of nanoscale junctions. Linking chemistry modifies the interfacial electrostatic potential and allows control of the dominant charge‐carrier type.
