摘要：
The optical pumping properties of two GaAs/AlxGa1-xAs quantum wells with similar well widths (∼6 nm) but differing by the introduction in one of them of a layer of Ino. 12Gao.88As between one barrier and the buffer were investigated. The strong increase of the value of the circular degree of polarization in this last sample with respect to the classical one is interpretated by the degradation of the interface quality due to the existence of a strain in the barrier. The absence of depolarization under a magnetic field in Voigt configuration may be explained by the cancelation of the electron Lande's factor for such well widths. © 1992.
