High photosensitivity and external quantum efficiency photosensors achieved by a cable like nanoarchitecture

The poor intrinsic flexibility of semiconducting ceramic materials hinders their applications in wearable electronics. Here, we present a highly efficient photosensor with extreme levels of bending and repeatable resilience based on cable-like structure. The ZnO@TiO₂ cable-like photosensor demonstrates an ultra-high external quantum efficiency (2.82 × 10⁶%) and photosensitivity (1.27 × 10⁵) upon UV light illumination at 254 nm, and a stability of 85% at the small curvature radius of 0.5 mm. Moreover, the ZnO@TiO₂ photodetector demonstrates extremely stable flexibility over 1000 bending cycles. This specific nanoscale architecture has future potential applications for soft integrated electronics.
