    Oral

    Lead-free ferroelectric materials with a tetragonal tungsten bronze (TTB) structure have attracted increasing attention due to their multifunctional potential in microelectronics and energy applications. In this study, Ba(2–x)Sr(x)GdFeNb₄O₁₅ (x = 0, 1, 2) ceramics were synthesized via the solid-state reaction route to investigate the influence of Sr substitution on structural and dielectric...

    Oral

    The study focuses on the synthesis and characterization of phosphate and borate glass systems modified with transition metal oxides such as molybdenum and tungsten. The incorporation of these oxides was found to influence the short- and medium-range structure of the glass network, leading to changes in coordination states and connectivity of structural units. Subsequent doping with europium...

  4. 184. Tailoring the Optical and Structural Properties of Si-Doped HfO₂ Films by Hydrogen-Assisted Magnetron Sputtering and Post-Annealing treatment
    Mr Dmytro Khomenkov (Mykola Gogol Nizhyn State University)
    07/11/2025, 11:15
    Oral

    The optical and structural properties of Si-doped HfO₂ thin films were systematically investigated as a function of deposition conditions and post-deposition annealing. The films were deposited by RF magnetron sputtering of a composite Si:HfO₂ target in pure Ar or Ar–H₂ plasma. Structural, optical, and luminescent characteristics were examined using spectroscopic ellipsometry,...
