摘要
On the basis of the quantum form of fluctuating-dissipative theorem and equation for fractals evolution of current carrier's concentration we obtained theoretical absorption, reflection and transmission spectra, and also we described process of light localization in a medium. Fluctuations have been described by the nonequilibrium functions of density of distribution of electrons. Dissipation has been characterized by using of equilibrium distribution of photons. Distribution of concentration of electrons, holes and clusters of particles was described by the system of differential equations. Photonic and exciton mechanisms of optical transition obtained by experiments are taken into account by the theory. It was shown, that by use of the theory we can describe spectra of amorphous, porous and chaotic nanostructured semiconductors.
