Chemical vapor transport synthesis of one-dimensional V2PS10 and its application in miniaturized UV sensors

Abstract

This study investigates low-dimensional materials as a potential solution for the miniaturization of electronic devices, addressing the challenges posed by bulk materials. Our research successfully synthesized high-quality V₂PS₁₀ crystals using the chemical vapor transport method and confirmed their dispersibility in various solvents and their potential for mechanical exfoliation. In addition, a UV-sensing device was fabricated to evaluate its performance. In particular, at a wavelength of 254 nm, the fabricated V₂PS₁₀-based UV sensor exhibited a stable response current of 1.5 pA, demonstrating rapid response characteristics. These results underscore the importance of stable synthesis techniques and highlight the potential of V₂PS₁₀ as a one-dimensional UV-sensing material, thereby indicating its applicability to miniaturize electronic components.
