In spintronics, inter-conversion between spin current and charge current is quite important. The inverse spin Hall effect (ISHE) is an effect that converts spin current to charge current. The efficiency of the conversion is partly determined by spin Hall conductivity (SHC). Recently, it was reported that the conversion efficiency in the ISHE and the SHC was largely modulated in ultrathin (2 nm) Pt by electric gating. In this study, we focused on ultrathin Cu, which possesses a weak spin-orbit interaction, instead of Pt, a strong spin-orbit interaction material. In this study the modulation of the current due to the ISHE and resistance were observed.
