摘要

We utilize the pentacene-based organic thin film transistor (OTFT) to act as a NH3 gas sensor. When the NH3 gas interacts with the OTFT, the drain current is reduced and the threshold voltage is negatively shifted toward a larger value. On the other hand, the subthreshold swing does not seem to be significantly influenced by the NH3 gas. From the analysis of gated-4-probes OTFT, the extracted contact resistance is increased and the estimated contact-less field-effect mobility is reduced, with the increase of the NH3 concentration. The reduction of the mobility and the increase of the threshold voltage are also discussed in this study.
