Abstract
Results are given of the experimental investigation of exciton absorption spectra in superthin films of PbI2 deposited on various substrates (glass, mica, metal). A theory of exciton states in thin polar films is developed, on the basis of which excitonic and band size effects are analyzed. The theory is in qualitative and quantitative agreement with the experiment.Keywords
