Thesis abstract
This PhD thesis focuses on the development of alternative plasmonic materials aimed at overcoming the limitations of conventional plasmonic systems. In particular, titanium oxynitride (TiON) and vanadium dioxide (VO₂) are synthesized as thin films using the pulsed laser deposition (PLD) technique. The plasmonic response of these materials is tailored during synthesis by adjusting the composition and morphology through controlled PLD parameters. Additional tuning is achieved through post-deposition thermal treatments. Finally, multilayered structures consisting of alternating plasmonic and dielectric materials are fabricated for energy harvesting applications.
Personal interest in my research theme
I have undertaken a PhD fellowship in the field of Physics of Matter, driven by a deep interest in nanostructured materials, which I find truly fascinating. Even small changes at the nanometric scale can dramatically alter a material’s overall response. Understanding the complex relationships between morphology, crystalline structure, composition, and other parameters with the resulting optical and plasmonic behavior is both a challenging and intellectually stimulating endeavor.
