| Abstract Scope |
Multicomponent equimolar oxides (MEOs) represent a novel class of single-phase materials formed by the mixing of metal oxides in equimolar ratios, yielding emergent properties distinct from their constituent binaries. The current study focuses on the single-phase spinel-structured MEOs composed of six 3d transition metal cations, synthesized in both bulk and thin film forms to investigate their properties. Bulk samples were fabricated via solution combustion synthesis (SCS), followed by compaction and sintering, while pulsed laser deposition (PLD) was employed for thin film growth. Structural and compositional characterization was conducted using a combination of techniques like XRD, SEM, TEM, XPS, and Raman spectroscopy. Functional properties such as optical bandgap, electrical conductivity, Seebeck coefficient, and thermal conductivity were measured to evaluate the materials' suitability for advanced electronic, photovoltaic and thermoelectric applications. These results contribute valuable insights into the correlation between multicomponent compositions, structural complexity, and functional performance in emerging oxide-based materials. |
