- •
NiO/ZnO nanowire arrays as a self-powered/active gas sensor have been realized.
- •
This sensing system can work without any external electric power source.
- •
Compared with bare ZnO, high and fast H2S response has been obtained.
- •
New coupling effect between the piezoelectric characteristic of ZnO and the conversion of NiO/ZnO heterojunctions can influence the piezoelectric screening effect.
