We demonstrate a hybrid ZnO nanoparticle decorated SWNT network device that can conductometrically differentiate between xylene isomers at room temperature with minimal interference from background VOCs. Field effect transistor measurements are conducted to identify the sensing mechanism which is attributed to enhanced SWNT transduction of chemical interaction with ZnO surfaces.
我们展示了一种混合 ZnO 纳米颗粒修饰的 SWNT 网络器件，它可以在室温下通过电导率区分二甲苯异构体，而对背景 VOC 的干扰最小。进行场效应晶体管测量以确定传感机制，该机制归因于 ZnO 表面的化学相互作用增强了 SWNT 的转换。
