Plasma-enhanced chemical vapor deposition is a promising technology for the preparation of materials in the form of thin films with controlled physical-chemical properties, which can be affected by changing input precursors or deposition conditions as needed. In this thesis, plasma nanotechnology was used to synthesize thin films on silicon wafers. Tetravinylsilane was chosen as a precursor for the synthesis of the films. In addition to pure tetravinylsilane, mixtures of tetravinylsilane with argon and mixtures of tetravinylsilane with oxygen were also used as input precursors for film deposition, in different proportions of the individual component in the deposition mixture. Using chemical analyses, specifically infrared spectroscopy, photoelectron spectroscopy and selected ion techniques, the chemical structure of the prepared films was examined in detail and the dependence of this structure on deposition conditions and input precursors was studied. This thesis confirms, that by changing effective power supplied to the plasma discharge and selecting different input precursors, it is possible to control chemical structure, and thus the properties of the prepared nanolayers.
