摘要：

We fabricated Al2O3/SiO2 stack structures with atomically thin Ti oxide layers at the interfaces using atomic layer deposition and investigated the capacitance-voltage (C-V) hysteresis of the metal-oxide-semiconductor (MOS) capacitors. We studied the effect of post-deposition annealing in the temperature range of 150 & DEG;C-500 & DEG;C on the C-V hysteresis and found that the Al2O3/SiO2-based stacks are thermally stable compared to ZrO2/SiO2- and HfO2/SiO2-based stacks. Using Al2O3/SiO2-based stacks, we investigated the impact of oxide layer thickness and gate electrode materials and studied pulse-induced current changes in MOS field-effect transistors.
