Abstract
An ambipolar hybrid organic-inorganic thin film transistor, consisting of pentacene and zinc oxide as semiconductors, is reported. The current-voltage characteristics in different operational modes are studied. The transistor is employed as a chemical vapor sensor, operating at room temperature. In p-channel accumulation mode, which is dominated by hole transport, a decrease of current with the introduction of analyte is observed, while in the n-channel triode mode, in which the current is predominantly contributed by electron transport, an increase in current with analyte delivery is observed. A qualitative model based on dipole interaction is proposed to explain the sensing activity.
