This paper contains the following concepts: definitions about polaron, concepts of
polarons, large polaron, small polaron, and development of quantum theory for electron
self-action potential in a system consisting of three contact different semi-conductor thin
layers, finding polaron potential energy, and studying the case in which an electron is
located inside the thin layer or on its surface. Studying the effect of dielectric anisotropy of
layers on electron-(hole) potential energy in the above mentioned thin layers.

There has been much interest in photonic and spectroscopic devices that are
useful for controlling transmission and reflection coefficients such as multilayer
thin films, photonic crystals, and various Bragg structures in the form of
molds or multilayer thin films.
In this paper we present the structural, optical and electrical characteristics of ZnO thin films grown for different parameters by the atomic layer deposition (ALD) method. The films were grown on glass and silicon substrates at low temperatures. We
