Influence of SAM Quality on the Organic Semiconductor Thin Film Gas Sensors
文献摘要：
Gas sensors based on organic semiconductors receive tre-mendous attentions owing to their advantages on high se-lectivity and room temperature operation.However,until now,most organic semiconductor based sensors still suffered from problems,such as low sensitivity,slow response/recovery speed and poor stability.In addition,a clear correlation between the sensing performance and the film property is still absent.Herein,we report the investigation on sensing performance of a series of organic films with various morphologies.By simply adjusting the quality of self-assembled monolayer(SAM)on the silicon wafer surface,we obtain organic semiconductor 6,13-bis(triisopropylsilylethynyl)pentacene(TIPS-pentacene)films with varied morphologies and different charge transport abilities.The film with a small grain size and a con-tinuous morphology presents the highest sensing performance to NO2,with a sensitivity up to 730％/ppm(ppm=parts per million,vo-lume ratio).We thus reveal that the high sensitivity of the organic film is evident related with the charge transport ability and initial conductivity of the films,as well as the morphologies of both modi-fication layer and the active films.
