ØAbstract
    
Ultrathin  oxide films have attracted a great deal of interest due to their importance in a
broad range of technological  applications, such as gas sensors, fuel cells,  protective
coatings, and heterogeneous catalysis.  Recent theoretical and  experimental  works of
catalysis demonstrated the importance of the electronic states of metal atoms adsorbed
on ultrathin oxide films grown on metal substrates. In this talk,  I will first present a brief
review of various properties obtained for metal-supported ultrathin oxide films. Next I will
show some ab initio calculation results carried out in our group to understand the physical  
properties of metal atoms on metal-supported ultrathin MgO films. Finally possible
implications for designable material systems will be discussed.
