                         subband structure in IV-VI lead-salt semiconductor asymmetric 
                         quantum wells (QW's) are obtained within the envelope function 
                         approximation and the Dimmock four-band k.p model for the bulk, 
                         around the four equivalent L points. Contrary to the III-V and 
                         II-VI QW's, the spin-orbit interaction in the these rocksalt QW's 
                         is purely Rashba, although multivalley and anisotropic. The Rashba 
                         splitting in these QW's is shown to be highly dependent on the 
                         structure parameters and can be much larger than those in similar 
                         III-V structures. In particular, specific results for the energy 
                         spectrum of Pb1-xEuxTe/PbTe/Pb1-yEuyTe QW's show that the Rashba 
                         splitting is approximately linear (and changes sign) with deltaQ, 
                         the difference between the band offsets at the two interfaces, 
                         independently of the valley and growth direction. The well width 
                         and k(parallel to) dependences of the Rashba splitting are also 
                         investigated, for the ground and excited states confined in IV-VI 
                         QW's, and experimental verification of the main predictions is 
                         discussed.",
