摘要：

The degree of circular polarization of photoluminescence from an n-type III-V-based [001] quantum well (QW) is calculated under an electric current flow in the well plane. It is shown that mixing of the states of light and heavy holes leads to circular polarization of photoluminescence during the propagation of light in the plane of the structure. The role of various terms that are linear in the wave vector in the electron energy spectrum is analyzed for the effects of spin orientation and emergence of circular polarization of radiation in the electric field.
