Fig. 6: Temperature-dependent characteristics of In2O3/ZnO heterojunction TFTs with Hyb_2 as a gate dielectric.

Temperature-dependent transfer curve a for the measurement temperature increased from 100 to 300 K in steps of 50 K and b for comparison of transfer curves at room temperature before and after the temperature-dependent measurement. c Arrhenius plots of the electron mobility, on current, and threshold voltage. Error bars represent the standard deviation from 10 devices.
