Outline of Final Research Achievements |
Material search and development of functions in Hg-Pt-O system were studied. Although Hg shows the unique bonding character, there are few reports of mercury including complex metal oxides since Hg is a highly volatile and toxic element. The samples were synthesized under a high pressure of 4GPa because enclosed condition is needed to react the raw materials of Pt and Hg oxides. Hg1-xPt3O6 (x=0-0.1) was an only stable compound in this system at least under the condition in this study. The compound shows semiconducting property with a very narrow gap of Eg=0.02eV assuming thermal activation-type conduction, and no magnetic signal was detected. Since it seems to be on the border between metal and insulator, metalization of this compound is expected by an application of pressure or career control with element substitution.
