| Outline of Final Research Achievements |
As a new application using spintronics, a research related to development of logic devices operated by carrier-driven spin currents was implemented. Spin currents in pentacene thin films, in p-type silicon and in vanadium oxide were tried to control densities of carriers with light irradiation, applying electrical field and controlling temperature, respectively.
Spin transport in a thermally evaporated pentacene film and in a degenerated p-type silicon were achieved at room temperature. Spin diffusion length and spin current relaxation time in thermally evaporated pentacene films at room temperature were estimated to be about 42 nm and about 150 ns, respectively.
