| Summary: | We report for the first time the successful synthesis of ZnO/WS<sub>2</sub> hybrid material using a combination of aerosol-assisted chemical vapor deposition (AA-CVD) and atmospheric pressure CVD techniques. The morphology and the composition of the grown films were investigated and the results confirm the co-existence of both materials. Moreover, gas-sensing results against 500 ppb of NO<sub>2</sub> revealed the influence of WS<sub>2</sub> material on the ZnO gas-sensing performance. The operating temperature shifted towards lower values, from 300 °C to 150 °C. Furthermore, at room temperature, the ZnO/WS<sub>2</sub> sensor was able to detect NO<sub>2</sub> at ppb level. |
