【Device Papers】Ga₂O₃ Solar-Blind Photodetectors: From Civilian Applications to Missile Detection and Research Agenda

      Researchers from the Berdyansk State Pedagogical University have published a dissertation titled "Ga₂O₃ Solar-Blind Photodetectors: From Civilian Applications to Missile Detection and Research Agenda" in Optical Materials.

Abstract

      This study offers a comprehensive review of gallium oxide (Ga₂O₃)-based photodetectors, emphasizing their applications in solar-blind UV detection and missile tracking systems. Using bibliometric, patent, and content analysis, research trends and technological developments were examined through an extensive review of scientific publications and patents. The analysis highlights the evolution of Ga₂O₃ photodetectors, particularly in fabrication techniques, device performance, and military applications. The study identifies critical research gaps, such as the need for optimized fabrication methods and the development of self-powered photodetectors. It proposes a research agenda to improve the efficiency and reliability of Ga₂O₃-based photodetectors for advanced applications, including missile detection and beyond.
