摘要：

The performance of organic thin-film transistors (TFTs) with a pentacene/fullerene(C-60)/pentacene (PCP) sandwich structure is presented. Using a 3.5 nn-thick C-60 layer inserted between the pentacene films, the obtained hole mobility is improved by more than six times. By applying atomic force microscopy, x-ray diffraction, Raman spectrum, and transmission line method analysis, one can reasonably infer that the smoother surface of the pentacene film covered with thin C-60 layer delays the phase transformation of the upper pentacene film, resulting in stronger intermolecular coupling and the reduction of channel resistance of the PCP TFTs from 3.03 to 1.72 M Omega, and, therefore, improving the device performance.
