Abstract
We present new improved pseudopotential calculations for PbSe and PbTe using several nonlocal corrections in addition to the local empirical pseudopotential. We discuss results for effective masses, Knight-shift measurements, and recent photoemission measurements. In addition to the optical properties in an energy range from 0 to 20 eV (which will be discussed in a subsequent paper), all the above experimental results can for the first time be explained consistently using one band-structure model.Keywords
