Abstract

Organic field effect transistors based on amorphous semiconducting polymers are used as highly effective sensors for the detection of low concentrations of NO2. The figure shows the experimental setup used to detect the toxic odor. The threshold voltage rather than the charge carrier mobility is seen to be greatly modified by exposure to NO2.
