Abstract

This study delves into the investigation of Pr7O12 thin-film-based Cu/Pr7O12/n-Si MIS Schottky barrier diodes, focusing on their enhanced photosensitivity. The research highlights the unique properties of Pr7O12 thin films, including their mixed-valence states, strong light absorption patterns, and high dielectric properties. The study employs the JNSP method for thin-film deposition, demonstrating its effectiveness in producing high-quality films with controlled stoichiometry and uniformity. Key findings include the optimization of the Pr7O12 film's molar concentration to enhance crystal growth and the achievement of a significant barrier height of 0.76 eV. The diodes exhibit outstanding photosensitivity of 220.72%, validating their potential for bio-optoelectronic platforms. The study concludes that Pr7O12 is a multifunctional interfacial material, and the JNSP method is a cost-effective, scalable, and ambient-compatible deposition route for high-performance photodetectors and biosensing devices.
