%X The spin-orbit split quantized states for electrons confined in IV-VI lead-salt asymmetric quantum wells (QWs), grown on both (100) and (111) substrates, are obtained analytically within the envelope function approximation with a k.p four-band model for the bulk. Non-parabolicity, anisotropy, and break of valley degeneracy are included. In (111) QWs, it is shown that for the valley along the growth direction the Rashba splitting is like the one in III-V QWs, i.e., isotropic and linear in k(parallel to) (for k(parallel to) similar to0). For the oblique valleys, contrary to the III-V case, a Rashba effect is obtained that is anisotropic and described by an effective magnetic field with nonzero component along the growth direction. Specific results for PbTe/PbEuTe asymmetric QWs with large Rashba splittings are shown.
