All-solution-processed n-type organic transistors using a spinning metal process

The synthesis of n-type organic thin film transistors (OTFT) was carried out by an all-solution-deposition process including source and drain metals as well as gate insulators and organic semiconductors. The organic semiconductors used are the soluble derivatives of C60. The OTFTs are well suited for a wide range of existing and future flexible circuits and display applications that require a simplified production process, low-weight and low-cost products. The solution processed organic semiconductor film in the OTFT were achieved using thermally curable organic gate insulator.
