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,

Optical Properties of Bismuth Nanostructures Towards the Ultrathin Film Regime
, 2019 Bulk bismuth presents outstanding optical properties, such as a giant infrared refractive index (n near 10) and a negative ultraviolet visible permittivity induced by giant interband electronic transitions. Although such properties are very appealing for

Advanced Functional Materials, EarlyView.Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...

Advanced Functional Materials, EarlyView.Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.
