      abstract     = {Ultrathin dielectric/insulating films on metals are often
                      used as decoupling layers to allow for the study of the
                      electronic properties of adsorbed molecules without
                      electronic interference from the underlying metal substrate.
                      However, the presence of such decoupling layers may
                      effectively change the electron donating properties of the
                      substrate, for example, by lowering its work function and
                      thus enhancing the charging of the molecular adsorbate layer
                      through electron tunneling. Here, an experimental study of
                      the charging of para-sexiphenyl (6P) on ultrathin MgO(100)
                      films supported on Ag(100) is reported. By deliberately
                      changing the work function of the MgO(100)/Ag(100) system,
                      it is shown that the charge transfer (electronic coupling)
                      into the 6P molecules can be controlled, and 6P monolayers
                      with uncharged molecules (Schottky–Mott regime) and
                      charged and uncharged molecules (Fermi level pinning regime)
                      can be obtained. Furthermore, it was found that charge
                      transfer and temperature strongly influence the orientation,
                      conformation, and wetting behavior (physical coupling) of
                      the 6P layers on the MgO(100) thin films.},
