Organic semiconducting perylene molecule was deposited as active layer on the FET pattern by using organic molecular beam deposition (OMBD) method. For the morphology and structure, we performed the atomic force microscopy, scanning electron microscopy, and X-ray diffraction experiments. From the I-V characteristics, bulk trap density, trap distribution, and electric field dependent mobility were estimated. Thin film field effect transistor based on perylene molecule was fabricated. From the results of the current modulation with different gate voltages of the FET, gate induced carrier concentration and field effect mobility were obtained. We observed Gaussian-like deep trap distribution, and that mobility was 3 × 10-7 cm2/Vs.
