Yaping Dan, Stephane Evoy, A. T. Charlie Johnson

摘要:

基于纳米线的化学气体传感器可以在临床分析、环境排放控制、爆炸物检测、农业储存和运输以及工作场所危险监测中找到广泛的应用。纳米线形式的传感器由于纳米线中的高表面积体积比和准一维限制而预期具有显著增强的性能。事实上,已经证明了具有ppb级灵敏度的基于纳米线的化学气体传感器。在这篇综述中,(i)纳米线的合成方法(ii)纳米线传感器的性能,(iii)化学电阻器,晶体管传感器及其传感机制,和(iv)组装技术的基本方面将进行总结和讨论。最后对纳米线化学气体传感器的研究前景进行了展望。

英文摘要:

Chemical gas sensors based on nanowires can find a wide range of applications in clinical assaying, environmental emission control, explosive detection, agricultural storage and shipping, and workplace hazard monitoring. Sensors in the forms of nanowires are expected to have significantly enhanced performance due to high surface-volume ratio and quasi-one-dimensional confinement in nanowires. Indeed, chemical gas sensors based on nanowires with a ppb level sensitivity have been demonstrated. In this review, the fundamental aspects on (i) methods of nanowire synthesis (ii) performance of nanowire sensors, (iii) chemiresistors, transistor sensors, and their sensing mechanism, and (iv) assembly technologies will be summarized and discussed. The prospects of the future research on chemical gas sensors based on nanowires will be also addressed.
