Conference paper


Photoemission of spin-polarized conduction electrons allows to analyze the spin relaxation processes inside the semiconductor and to directly evidence the internal precession related to the lack of inversion symmetry in III-V compounds. It is the principle of GaAs polarized electron sources.
