N. Kramar, V. Kramar, B. Nitsovich
Imaginary and real parts of the dielectric function of the layer semiconductor
PbI2 were found using the result of the pseudopotential method zone structure
of electron energy spectra calculations. This enabled to calculate optical
parameters of the crystal, in particular, absorption, and reflectivity
and refraction spectra. There is a good agreement between the result of
the reflectivity spectrum calculations and the experiment data.
Key words: layer crystal, lead iodide, optical spectra
