| Outline of Final Research Achievements |
In this work, we attempted to observe spin-charge conversion caused by inverse Edelstein effect associated with the spin-splitting in noncentrosymmetric bulk semiconductors. While we first tried spin-pumping experiments for ferromagnet/semiconductor interfaces, it turned out that the contribution from interface is more significant than the underlying bulk itself and we couldn't observe the selection rule as expected. To overcome this issue, we have performed the magneto-photocurrent measurements, and observed the photo-induced voltage signals along the direction consistent with the symmetry of noncentrosymmetric bulk crystal structures.
