High‐Responsivity Self‐Powered Photoelectrochemical UV Photodetector Based on Integrated Self‐Supporting SiC/ZnS Heterojunction Nanowire Arrays

In the realm of photodetector (PD) technology, photoelectrochemical (PEC) PDs have garnered attention owing to their inherent advantages. Advances in this field depend on functional nanostructured materials, which are pivotal in improving the separation and transport of photogenerated electron-hole pairs to improve device efficiency. Herein, a highly photosensitive PEC UV PD is built using integrated self-supporting SiC/ZnS heterojunction nanowire array photoelectrodes through anodization and chemical deposition. Compared with the original SiC nanoarrays, the optimized SiC/ZnS-25 nanoarrays exhibit high photocurrent density (D
