Abstract

O₂ gas sensing behaviors are studied in picene thin film field-effect transistors (FETs) with hydrophobic polymer (Cytop™ or polystyrene) coated SiO₂ gate dielectrics. Picene thin film FETs show a rapid reduction of hysteresis in transfer curves recorded in forward and reverse measurement modes, compared to a picene FET with hexamethydisilazane- coated SiO₂. The picene FETs show very sensitive O₂ gas sensing effects down to ∼10 ppm. A quantitative analysis is presented of the gate voltage (V_G) dependent mobility induced by O₂ exposure, i.e., the suppression of drain current at high V_G.
