The structure optimization of the carbon nanotube film cathode in the application of gas sensor
نویسندگان
چکیده
The carbon nanotube (CNT) film is used to fabricate the novel carbon nanotube film cathode (CNTFC) gas sensor, and the working voltage of the novel sensor at atmospheric pressure decreases to several hundred volts from the value of more than thousand volts of the traditional discharge gas sensor, however it is limited by that the space charge in the gap is very hard to diffuse after the breakdown of the gap. This makes the gap i c d a w u ©
