dc.description.abstract | Hydrogen plays a crucial role in several oxide semiconductors, where the amount of hydrogen significantly influences the device performance. Thus, its manipulation in oxide semiconductors is important for device performance. In our investigation, we studied the effect of hydrogen on defects in In-Ga-Zn-O semiconductor thin-film transistors (TFTs), as it varies with Al2O3 atomic layer deposition temperature. We found that the total trap-density (N-tot) extracted by the sub-threshold slope and the trap density (N-t) measured by low-frequency noise (LFN) as well as the density-of-states analyzed by capacitance-voltage decreased with increasing amounts of hydrogen in the oxide semiconductor. Given that LFN data show that mobility fluctuation is the major origins of noise and the front channel of TFT is a major carrier transport region, our results indicate that hydrogen effectively passivates the defects in front channel of oxide semiconductor and contributes to achieving superior device performance | - |
