ABSTRACT
The morphology and electronic structure of ultrathin PbO films on silicon-supported Pb islands have been investigated with a low temperature scanning tunneling microscope. It is found that the PbO film acts as an insulating layer to electronically decouple the adsorbates from the metallic substrate. Due to the increased lifetime of spin excitation, the Zeeman splitting of individual manganese phthalocyanine molecules adsorbed on PbO could be detected with spin-flip inelastic tunneling spectroscopy. The ultrathin insulating films like PbO provide an effective way to control the electronic coupling in the nanometer scale.
