The Modification of Optical Properties of the Surfaces by the Glancing Angle Deposition Technique

The paper considers the optical properties and structure of thin films of titanium dioxide formed by the glancing angle deposition method. It was show that this method allows the formation of coatings having a significantly lower refractive index than that of the initial material. Thus, the experimentally obtained value of the refractive index of thin films of titanium dioxide was ~1.2, which is almost two times less than that of a polycrystalline material. This allows you to use this method to produce the coatings with a variable refractive index using only one material, changing the geometry of the deposition process only.
