High-Performance UV-Visible-IR Photodetectors Based on PVP/SnS 2 Nanofiber@n-Si Heterojunctions: Unveiling the Role of Interface Dynamics and Morphology

In this work, we fabricated a PVP/SnS<sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> nanofibers (NFs)@n-Si heterojunction-based photodetector by loading SnS<sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> onto PVP nanofibers using the electrospinning technique and investigated its optoelectronic properties with the help of UV, IR and visible illumination. The heterojunction gave an extrao
