- •
A Schottky junction-based gas sensor is designed to considerably improve the response values towards nitro-explosive vapors.
- •
The ZnO/rGO core/shell micro-Schottky junction-based gas sensor shows, highly sensitive, real-time detection toward TNT, DNT, PNT, RDX and PA vapors.
- •
Superior anti-interfering performance is shown even towards interfering gases of ppm level.
- •
The enhanced sensing performance is attributed to the micro-Schottky junction built at the interface of ZnO and rGO.
