| Abstract [eng] |
Investigation and characterization of nano-sculptured thin films are presented in thesis. Investigation includes the formation of columnar structures by glancing angle deposition, evaporation of porous silica layers and conformal evaporation of metal on biological surfaces. Results indicate, that columnar structures exhibit birefringence, which can be controlled by changing deposition angle. Such coatings can be used during the formation of waveplates. Also, chiral structures can be deposited by slowly rotating the substrate, placed at glancing angle. Such coatings exhibited the selectivity for circular polarization. Vertical columns can be formed by using fast substrate rotation. The refractive index of such coatings can be tailored by changing the angle of deposition. Antireflection and high reflection coatings have been produced by controlling the refractive index of substituting layers. Investigation shows, that silica coatings exhibit high resistivity to laser radiation and can be used in high power optical systems. Also, conformal evaporation of metal on butterfly wing provides a way to replicate, study and exploit hidden morphologies of biological surfaces. |
