Band Structure and Scattering Mechanisms (Theory and Conclusions from Experimental Data)
The first calculation of the energy band structure of one of the chalcogenides, PbS, was carried out by Bell et al.  at a time when the experimental data on the properties of lead chalcogenides were scant and the calculation methods were imperfect (Bell et al.  used the method of cells without relativistic corrections). The results of their calculation were contradicted by later experimental data. An energy band structure which is in agreement with experiment was derived theoretically only fairly recently [467–471], after the accumulation of a considerable amount of experimental data on the band structure of all three lead chalcogenides.
