| Outline of Final Research Achievements |
As shown because Bi is a semimetal, in its bulk state, the temperature dependence of conductivity σ behaves like a metal near room temperature. When Bi is nanowired and the wire diameter is less than 300 nm, experiments have confirmed unique transport phenomena, such as a large increase in conductivity in the low-temperature region. This study reveals that the change in the scattering process by Bi nanowiring results in a measured resistivity temperature dependence, as opposed to the metallic resistivity temperature dependence of Bi, which is a semi-metal.
