摘要：

The dielectric response and electrical properties of junctions based on self-assembled monolayers (SAMs) of the form S(CH2)(11)X 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 fourfold increase of the dielectric constant (epsilon(r)) with increasing polarizability of X are found.
