PANI was synthesized with and without ZnO nanoparticles. FET production was carried out by producing PANI and PANI/ZnO channel structures on Si/SiO2 (285 nm) substrate by the optical lithography method. The electrical responses of the produced sensors against hydrogen (H2) gas were determined by measuring the source-drain current at 25 ˚C, 50 ˚C and 80 ˚C while applying the +20 V gate voltage to the transistors. It has been observed that the sensors which were produced by PANI channel, detect H2 gas but adding ZnO nanocomposite into PANI improves the detection performance. Besides, unlike the PANI channel FET sensor, it has been determined that PANI/ZnO channel FET sensors operate with an excellent performance at room temperature.}, number={1}, publisher={Erciyes Üniversitesi}, organization={YOZGAT BOZOK ÜNİVERSİTESİ PROJE KOORDİNASYON UYGULAMA VE ARAŞTIRMA MERKEZİ}
