摘要

We reported an amorphous InGaZnO thin-film transistor using stacked gate dielectrics of GeO₂/TiO₂ on flexible polycarbonate substrate. The flexible TFT showed a low threshold voltage of 2.2 V, small sub-threshold swing of 256 mV/decade, an field effect mobility of 4 cm ²/Vs, and a good I_on/I_off ratio of 3.7×10⁵. The flexible TFT with low operation voltage and high drive current could be attributed to the combined effect of flat plastic substrate, large band-gap GeO₂ and higher-K TiO₂.
