金属氧化物半导体（MOS）纳米膜在电子器件方面具有巨大的潜力。本论文采用卷绕技术制备了管状SnO2纳米膜，并将其作为化学电阻式气体传感器的敏感元件进行了研究。由于SnO2纳米膜的可及性和大量的吸附氧物种，基于SnO2纳米膜的传感器显示出高和快速的响应，选择性检测丙酮，以及良好的重复性，稳定性和低检测限的ppb级。管状纳米膜结构具有良好的传感性能，为化学气体传感器提供了一个新的平台。这项工作将推动集成的管状MOS纳米膜到一个真实的微型传感器的实验室在管的概念的基础上。(C)2018爱思唯尔B.V.保留所有权利。
Metal oxide semiconductor (MOS) nanomembranes hold a great potential for electronic devices. In this work, tubular SnO2 nanomembranes were fabricated by the rolled-up technology and investigated as the sensing element for chemiresistive gas sensors. Due to the high accessibility to both surfaces of nanomembranes and the large amount of adsorbed oxygen species, the sensor based on SnO2 nanomembranes displayed high and fast response for selective detection of acetone, as well as good repeatability, stability and low detection limit of ppb-level. The very good sensing performances derived from the tubular nanomembrane structure suggests a new platform that can be used for chemical gas sensors. This work will drive the integration of tubular MOS nanomembranes into a real microsensor based on the lab-in-tube concept. (C) 2018 Elsevier B.V. All rights reserved.
