摘要：

The authors report on the rubrene polycrystalline film growth for its thin film transistor (TFT) applications. Amorphous rubrene thin film was initially obtained on 200-nm-thick SiO2/Si substrate at 40 degrees C in a vacuum chamber by thermal evaporation but in situ long time postannealing at the elevated temperatures of 60-80 degrees C transformed the amorphous phase into crystalline. Based on an optimum condition to cover the whole channel area with polycrystalline film, the authors have fabricated a rubrene TFT with a relatively high field effect mobility of 0.002 cm(2)/V s, an on/off ratio of similar to 10(4), and a low threshold voltage of -9 V.
