New Materials, Compounds and Applications

In this study, we analyze the applicability of Ga₂O₃ and TiO₂ oxide in materials science and radiation-related materials science, focusing on their electrical and thermophysical properties, surface morphology, irradiation-induced disordering and phase transformations under various irradiation conditions. Nanoscale gallium oxide (Ga₂O₃) and titanium oxide (TiO₂) are increasingly recognized as promising materials in advanced research and technological applications due to their distinctive physical properties. β-Ga₂O₃ and TiO₂, as promising oxide materials, demonstrate significant potential for application in radiation and ion implantation environments relevant to nuclear and space technologies. The primary objective of this study is to investigate the critical physical and chemical factors influencing the formation mechanism of “defect structure” in TiO₂ nanoparticle/Ga₂O₃-based materials. Our findings reveal that nanoparticle-based Ga₂O₃ exhibits significant photoelectrochemical detector properties for ultraviolet radiation detection, making it a viable candidate for Schottky Barrier Diodes with high potential and photocatalytic water-splitting systems for green hydrogen production, owing to its exceptional thermal stability. Additionally, the study explores the potential application of TiO₂ nanoparticle/Ga₂O₃ composites as coating materials for space and nuclear technologies, emphasizing the optimization of synthesis, processing and irradiation conditions to extend material service life in mixed irradiation environments.
