| Outline of Final Research Achievements |
We have investigated the effect of atom/molecule adsorption on electrical conduction of metallic ultrathin films by a four-point probe applicable to in-situ measurement under ultrahigh vacuum condition and temperature-dependent measurement in a wide range of 9-350 K. The adsorption of iron-phthalocyanine (FePc) on a double-atomic-layer indium film led to not only the increase of sheet resistivity but also the decrease of temperature coefficient. Because we observed little change in Fermi surface mapping by angle-resolved photoelectron spectroscopy, our results indicate FePc-induced modulation of electron-phonon coupling in the indium ultrathin film. We also studied the effect of adsorption of transition metal atoms (Ni and Co) on a lead monolayer with large Rashba spin splitting in metallic states. While residual resistivity was increased by the adsorption, the Kondo effect was not observed in the measured temperature range of 9-80 K.
