Abstract

A bottom contact organic field effect transistor (OFET) was fabricated with poly(3-hexylthiophene) (P3HT) as the channel semiconductor. P3HT thin film was deposited onto a SiO₂/n-Si substrate by spin coating and electrical characteristics of the P3HT-FET were investigated in a nitrogen flux. A change in the saturation drain-source current (IDS) was observed when device was exposed to different concentrations of nitrogen dioxide (NO₂) gas. It was found that the variation in the IDS was remarkable with NO₂ injected in a short time.
