Outline of Final Research Achievements

Spintronics, which utilize electron and charges, attract much attentions which enable us to operate semiconductor-based electronics with low-energy consumption. In this project we tried to develop spintronic devices made by organic semiconductors. The way to inject spins into organic semiconductors are as follows: 1) Spin pumping-induced spin injection into organic semiconductors, 2) Light-emitting diode structure with ferromagnetic contacts. We observed that there are signatures of spins which is induced to organic semiconductors.
