The dielectric response and electrical properties of junctions based on self‐assembled monolayers (SAMs) of the form S(CH2)11X can be controlled by changing the polarizability of X (here X = H, F, Cl, Br, or I). A 1000‐fold increase in the tunneling rate and a four‐fold increase of the dielectric constant (ε r) with increasing polarizability of X are found.
