Popis: | We report the dependence of optical rectification and shift currents in unbiased GaAs(111) on the excitation beam polarization using THz emission spectroscopy. When exciting slightly above bandgap with elliptically polarized light, the emission is strongly influenced by spin-polarized electrons. |
