Essay

The dissertation is devoted to: research of physical mechanisms of optoelectronic properties of functionalized silicon epoxy nanocomposite based on epidiane 5 and hydrophilic and hydrophobic silicon nanoparticles; photovoltaic properties of SiGe films covered with layers of amorphous and polycrystalline silicon; photoelectric properties of Si surfaces with Ge quantum dots; terahertz conductivity of ultrathin Au films on 3 - mercaptopropyl (MPTMS) -coated silicon surfaces; photovoltaic properties of sonochemically functionalized heteronanostructures of Si / Ge; sonochemical functionalization of CaSiO3–SiO2–Si; photoelectric properties of heterostructures Si / ZnO and Si / NiO. The purpose of the work is to establish the mechanisms of functionalization and the resulting changes in optoelectric parameters in silicon hetero-nanostructures of various types, including thin and ultrathin layers and embedded quantum dots. Actuality of theme. Taking into account the needs of modern electronics, alternative energy and the development of the fundamental theory of surface phenomena in semiconductor structures, the question arises of a more detailed study of complex hetero- and nano-structures, which would be able to change their parameters depending on the technical or experimental requirements. These needs can be satisfied by the creation of hetero- and nano-structures, as a primary link, and their further functionalization.
