A promising approach was proposed to enhance the responsivity of a ZnO nanowires array based photodetector though piezo-phototronic effect.
- class="label">•
The ZnO nanowires serve as piezoelectric functional layer and light-trapping material.
- class="label">•
Using polarization charges at interfaces under strain, the local Schottky barrier height and the responsivity of the device can be modulated.

The fabricated detector allows simultaneous and identical changing behavior of Schottky barrier heights at the two contacts.
