Abstract

Optical properties of thin films of poiar dielectrics and semiconductors were the subject of a great number of scientific and technical publications. However, during the last twenty years new experimental results have been obtained which enriched our notions about the interaction of electromagnetic radiation with the condensed state of a substance. The most important of them are: -detection of radiative surface polaritone in thin crystalline films of polar semiconductors 12; detection of strong interaction between elementary excitations in adjacent media (a film and a substrate) 35; detection of Raman scattering at the frequencies of wave-guide "and of interference polari tons; observation of the spectra of thermostimulated radiation, absorption, luminescence and resonance Raman scattering (RRS) at the frequencies of interference modes (IMs) in filn -detection of strong resonance interaction between local vibrations of impurity atoms and IMs in films In the present paper an attempt is made to explain the totality of the experimental data the author is aware of on optical properties of the ifims of different thicknesses from super thin to bulk single crystals obtained by various optical spectroscopy methods within the framework of macroscopic linear crystal optics in the polariton language.
