The electron energy levels of lead iodide are computed using the tight binding method and screening the exchange crystal potential with the dielectric function. Spin-orbit splitting and other relativistic effects are introduced as perturbations. The energy band structure so obtained is related to the optical absorption spectrum and the first exciton and saddle point peaks are interpreted.

Abstract
The electron energy levels of lead iodide are computed using the tight binding method and screening the exchange crystal potential with the dielectric function. Spin-orbit splitting and other relativistic effects are introduced as perturbations. The energy band structure so obtained is related to the optical absorption spectrum and the first exciton and saddle point peaks are interpreted.File in questo prodotto:
