UV-curable organic-inorganic hybrid gate dielectrics for organic thin film transistors

► Inorganic-organic hybrid materials were synthesized by a sol-gel method. ► The microstructure and dielectric properties of hybrid films were studied. ► The hybrid dielectric layer exhibited high performance characteristics. ► High mobility of 2.5 cm2/V s and on/off ratios (>105) with OTFT were achieved.
