Outline of Final Research Achievements

The structures and properties of tellurium which has two-folded chain structures and second order structure were investigated. In order to clear the properties the Te nanoparticles were produced and measured at the liquid nitrogen temperature. The primary structure is preserved even in the nanoparticles, but the covalent bond length shortens. However, the secondary structure collapses. The Te nanoparticles deposited on Si substrate have hemispheroid shape.
