제목 Crystalline Nanostructure and Morphology of Tri-IF-dione for High-performance Stable N-type Field-Effect Transistors
초록 The device performance and stability of n-type OFET based on hexafluoro-indeno-fluorene-dione were investigated. The electrical characteristics of TriF-IF-dione FETs were optimized by controlling the dielectric surface properties via insertion of organic interlayers, such as SAMs or polymeric layers at the semiconductor/SiO2 dielectrics interfaces. In particular, a thin PS layer surface provided a device that performed well. The improvements in the performance of TriF-IF-dione OFET conveyed by the PS interlayers were examined in terms of the crystalline nanostructure and charge modulation effects in the channel. These properties were correlated with, respectively, the hydrophobicity and the electron-donating characteristics. The TriF-IF-dione FETs with a PS interlayer showed excellent electrical stability attributed to high activation energies for charge trap creation. A complementary inverter comprising both pentacene and TriF-IF-dione was successfully demonstrated.
