Photocurrent in structures with quantum wells with an optical orientation of free carriers
Ivchenko E. L. , Lyanda-Geller Yu. B. , Pikus G. E.
In media without an inversion center the spin relaxation and Larmor spin precession of optically oriented, thermalized carriers induce a current which is proportional to the spin polarization. The magnitude of this effect in the semiconductor structures GaAs/AlGaAs is determined.
