Sensing performance of gas sensors fabricated from controllably grown ZnO-based nanorods on seed layers
Abstract ZnO nanorods (NRs) grown on different ZnO seed layers deposited at various Ar–$ O_{2} $ ambient conditions, and the morphologies of the seed layers that affect their response to nitric oxide (NO) gas were investigated. The sensing performance of the devices fabricated with the seed layers d...

| 520 | |a Abstract ZnO nanorods (NRs) grown on different ZnO seed layers deposited at various Ar–$ O_{2} $ ambient conditions, and the morphologies of the seed layers that affect their response to nitric oxide (NO) gas were investigated. The sensing performance of the devices fabricated with the seed layers deposited under an $ O_{2} $-rich condition tends to deteriorate. We believe that the surface roughness, grain size, and defect concentration of the seed layer are responsible for this phenomenon. Despite the response to the gas was found to be less dependent on NR length, the gas sensing response is significantly dependent on the oxygen vacancy concentration and the exposure of the NR structure to the NO gas ambient surface. Excellent gas response (57.5% at 1 ppm and 7.1% at 100 ppb of NO gas) was achieved at room temperature—superior to the response presented by other proposed methods. This study not only proposes the potential of ZnO-NRs for high-performance NO gas sensor devices but also offers a simple and low-cost method to optimize the response without using any catalyst and additional treatment. | ||

sensing performance of gas sensors fabricated from controllably grown zno-based nanorods on seed layers |

Sensing performance of gas sensors fabricated from controllably grown ZnO-based nanorods on seed layers |
| abstract |
Abstract ZnO nanorods (NRs) grown on different ZnO seed layers deposited at various Ar–$ O_{2} $ ambient conditions, and the morphologies of the seed layers that affect their response to nitric oxide (NO) gas were investigated. The sensing performance of the devices fabricated with the seed layers deposited under an $ O_{2} $-rich condition tends to deteriorate. We believe that the surface roughness, grain size, and defect concentration of the seed layer are responsible for this phenomenon. Despite the response to the gas was found to be less dependent on NR length, the gas sensing response is significantly dependent on the oxygen vacancy concentration and the exposure of the NR structure to the NO gas ambient surface. Excellent gas response (57.5% at 1 ppm and 7.1% at 100 ppb of NO gas) was achieved at room temperature—superior to the response presented by other proposed methods. This study not only proposes the potential of ZnO-NRs for high-performance NO gas sensor devices but also offers a simple and low-cost method to optimize the response without using any catalyst and additional treatment. © Springer Science+Business Media, LLC, part of Springer Nature 2020 |
