基于酞菁铜单晶纳米线气体介质场效应晶体管（FET），构建了一种快速响应、完全恢复的室温高灵敏SO2传感器。气体介质暴露出的导电通道是对SO2的高灵敏度的原因，SO2分子的吸附显著提高了场效应迁移率。这些结果不仅为开发新的SO2传感器开辟了新的机会，而且为提高有机FET的性能提供了一种有效的方法。
A room-temperature highly-sensitive SO2 sensor with fast response and complete recovery is constructed based on gas dielectric field-effect transistor (FET) of CuPc single crystalline nanowire. The exposed conductive channel by gas dielectric is responsible for the high sensitivity to SO2 and the adsorption of the SO2 molecules dramatically enhances the field-effect mobility. These results not only open up new opportunities to develop new SO2 sensors, but also provide an efficient way to improve the performance of organic FETs.
