摘要：

We calculate evanescent waves in GaAs-like III-V semiconductors throughout the forbidden band gap taking into account both the absence of inversion center and the spin-orbit coupling. We find that the evanescent energy bands are spin-split and that the evanescent wave functions only exist in limited energy and wave-vector domains. Such tunnel barriers can be used as solid-state spin injectors.
