Versatile p-type metal oxide nanowire array for ultra-sensitive volatile organic compound sensor |
| 초록 |
The demand for early detecting systems of sub ppm level volatile organic compounds (VOCs) is drastically increasing in the health care and environmental markets. Among the various methods, the chemiresistors based on metal oxide (MOX) have proven to be promising due to their cost efficiency and flexibility in production. Despite consider progress in these area, p-type MOX nanostructure which show various promising potential for practical applications is still in the early stages of development. Here, we show that fabrication of versatile p-type MOX (CuO, NiO, Cr2O3) nanowire array consists of 5nm below nanoparticles with simple lithographic technique. Due to high volume-to-surface area ratio of nanowire, highly sensitive VOCs sensing performance is shown. More important is that versatile transition metal can be patterned and converted to semiconducting oxide with single universal process, accordingly, multi-channel devices can be simply fabricated by only varying the metal sources. |
