Title: Single-molecule chemistry and spectroscopy on ultrathin insulating films
Speaker: Dr. Yousoo Kim ( RIKEN, Japan )

Place: Natural Science 1, Room No. 31214
Abstract: Ultrathin insulating films grown on metal substrate has been a subject of great
interest for investigation of individual adsorbate atoms and molecules using a scanning
tunneling microscope (STM), because of electronic decoupling between the adsorbate
and supporting metal surface under an STM junction. Here, I will talk about two
representative works that we have done about energetics at the single-molecule
interfaces on the ultrathin insulating films.
The chemical reactivity of a water molecule on an
ultrathin MgO film supported by the Ag(100) substrate
depends greatly on film thickness and be enhanced
compared to that achieved with their bulk counterpart .
The change of chemical reactivity of ultrathin MgO film
depending on the film thickness can be explained by the
strengthening of the interaction between the oxide and
metal interface layers . Our results clearly show that
such structural imperfections at the interface can improve
the chemical reactivity of the MgO film supported by an
Ag substrate .
Optical properties of a single metal-free phthalocyanine (H2Pc) molecule on the
2-ML thick NaCl film supported by Ag(111) have been also studied by scanning
tunneling luminescence spectroscopy. I will discuss about the single molecule reaction
of an H2Pc molecule with tunneling electrons and accompanied optical property
changes in a single-molecule luminescence spectra.
