WebSep 1, 2024 · Because of the inverse spin Hall effect (ISHE), ... The photoinduced ISHE was observed in a Pt/GaAs hybrid structure. In the GaAs layer, circularly polarized light generated spin-polarized carriers, inducing a pure spin current into the Pt layer through the interface. This pure spin current was converted into an electrical voltage due to the ... http://qspin.phys.s.u-tokyo.ac.jp/
Photoinduced inverse spin-Hall effect: Conversion of light …
WebNov 8, 2024 · The inverse spin Hall effect (ISHE) has been recently demonstrated through the photoinduced inverse spin Hall effect (PISHE), where a focused laser normal to the device plane generates photocurrent that depends on the helicity of the photoexcitation. Here, we have employed a finite element method to rigorously simulate the helicity … WebDec 27, 2016 · We perform photoinduced inverse spin-Hall effect (ISHE) measurements on a Pt/Ge(001) junction at room temperature. The spin-oriented electrons are photogenerated at the Γ point of the Ge Brillouin zone using circularly-polarized light. After the ultrafast Γ − L scattering in the Ge conduction band, which partially preserves the spin polarization, … cephalexin if allergic to penicillin
