Circular photogalvanic effect in an inversion-symmetry-broken bilayer germanium nanosheet
Taiki Nishijima, Ei Shigematsu, Ryo Ohshima +7
Spin-to-charge conversion in monolayer and bilayer germanium(Ge) nanosheets was demonstrated via the circular photogalvanic effect (CPGE). The CPGE current generated in a spin-spli…
Electrical transport properties of atomically thin WSe2 using perpendicular magnetic anisotropy metal contacts
S. Gupta, R. Ohshima, Y. Ando +3
Tungsten diselenide, WSe2 shows excellent properties and become very promising material among two dimensional semiconductors. Wide band gap and large spin-orbit coupling along with…
Gigantic Anisotropy of Self-Induced Spin-Orbit Torque in Weyl Ferromagnet Co2MnGa
Motomi Aoki, Yuefeng Yin, Simon Granville +6
Spin-orbit torque (SOT) is receiving tremendous attention from both fundamental and application-oriented aspects. Co2MnGa, a Weyl ferromagnet that is in a class of topological quan…
Spin transport and spin conversion in compound semiconductor with non-negligible spin-orbit interaction
Akiyori Yamamoto, Yuichiro Ando, Teruya Shinjo +2
A quantitative investigation of spin-pumping-induced spin-transport in n-GaAs was conducted at room temperature (RT). GaAs has a non-negligible spin orbit interaction, so that elec…
Spin transport in non-degenerate Si with a spin MOSFET structure at room temperature
Tomoyuki Sasaki, Yuichiro Ando, Makoto Kameno +5
Spin transport in non-degenerate semiconductors is expected to pave a way to the creation of spin transistors, spin logic devices and reconfigurable logic circuits, because room te…
Observation of spin-charge conversion in CVD-grown single-layer graphene
Ryo Ohshima, Atsushi Sakai, Yuichiro Ando +4
Conversion of pure spin current to charge current in single-layer graphene (SLG) is investigated by using spin pumping. Large-area SLG grown by chemical vapor deposition is used fo…
