Abstract

This presentation will explore polycrystalline and amorphous SNO films synthesized via chemical vapor deposition (CVD) under primary vacuum conditions—an
approach never previously reported in the literature. We employ a novel chemical strategy combining metallic element reduction with cation deficiency engineering, wherein the Sr/Nb ratio is deliberately reduced to modulate the Nb⁵⁺/Nb⁴⁺ oxidation state and optimize electrical conductivity without external doping. This relaxed vacuum requirement
enables low-temperature processing while eliminating epitaxial substrate constraints, significantly enhancing scalability for industrial implementation.

Short Bio/CV

PhD candidate affiliated with the LMGP and CROMA laboratories. My research focuses on the development and optimization of niobium-based transparent conducting oxides (TCOs) using Pulsed Liquid Injection Metal–Organic Chemical Vapor Deposition (PLI-MOCVD). My work involves the synthesis of thin films, the control of their composition and crystallinity, and the investigation of their structural, electrical, and optical properties for potential applications in optoelectronic and energy-related devices.
