Abstract
Three ‑ dimensional (3D) tetrapodal ZnO (t ‑ ZnO) networks are promising for multifunctional sensing but often suffer from poor interparticle connectivity, which limits charge transport and sensitivity. We introduce interconnection density as a tuneable design axis governing both electronic and sensing behaviour in 3D semiconductor frameworks. Through a UV ‑ driven photoelectrochemical approach, nanoscale ZnO bridges are selectively formed between tetrapodal arms, enabling controlled tuning of network connectivity. The optimized interconnected networks show a 25 ‑ fold enhancement in UV response and highly efficient gas detection (10x enhancement), while preserving low ‑ cost and scalable fabrication. Interconnection engineering thus emerges as a general route toward next ‑ generation multimodal sensors [5].
