Abstract

We fabricated perylene-based organic thin-film transistor (OTFT) with an octadecyltrichlorosilane (OTS) monolayer in an ultrahigh vacuum condition. By current-voltage characteristics, the saturation current and the field effect mobility of OTS-OTFT (goldperyleneOTSSi O2 p+ -Si) increased over ∼100 times in comparison with normal-OTFT (goldperyleneSi O2 p+ -Si), and on/off ratio increased over ∼100 times. The saturation current, field effect mobility, and on/off ratio were >1 μA, 0.042 cm2 V s, and > 106, respectively. The uniformity of the OTS layer was confirmed by x-ray reflectivity. Perylene thin films on Si O2 and OTSSi O2 were compared by atomic force microscopy, scanning electron microscopy, x-ray diffraction, and x-ray photoscopy.
