Optical deformation potentials for PbSe and PbTe

The values of optical deformation potentials (Du and Dd) for PbSe and PbTe are analyzed using absorption, luminescence and X-ray diffraction data on high quality, deep quantum well PbSe/PbSrSe and PbTe/PbEuTe structures. It is important for these evaluations to use the val...
