SYNTHESIS AND INVESTIGATION OF THIN TiO₂ FILMS, DOPED WITH COPPER NANOPARTICLES

Вестник Северо-Кавказского федерального университета, 2022
Thin films of titanium dioxide, doped with copper nanoparticles, were synthesized by the method of deposition on the rotating substrate. The obtained films were dried at room temperature and at temperature of TiO2 calcination and studied by ellipsometry,

Photolyzable Polymer Brushes: Subtractive 3D Structuring of Surfaces Using Water and Light. [PDF]

Angew Chem Int Ed Engl
Facile structuring of polymer brushes is achieved by flipping the process from controlled growth to controlled brush photolysis. Using surface‐initiated radical ring‐opening polymerization of cyclic monomers with photocleavable cyclobutane rings, photodegradable targets are embedded into the polymer chains. The enabled continuous subtractive patterning

Spectroscopic Ellipsometry of Conducting Anisotropic Pedot thin Films. [PDF]

Macromol Rapid Commun
We measure the optical response of poly[3,4‐ethylenedioxythiophene] thin films through the combination of polarized photon spectroscopies (variable‐angle ellipsometry, UV–mid‐IR reflectance and transmittance) and wide‐angle X‐ray scattering, revealing anisotropic optical response and conductivity and enabling structural modelling of chain and π‐system ...

Stable dielectric response of low-loss aromatic polythiourea thin films on Pt/SiO2 substrate [PDF]

Journal of Advanced Dielectrics, 2016
We have investigated dielectric properties of aromatic polythiourea (ArPTU, a polar polymer containing high dipolar moments with very low defect levels) thin films that were developed on Pt/SiO2 substrate.

Chiral Phase Change Nanomaterials

Advanced Functional Materials, EarlyView.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...
