Abstract
The capacitance-voltage (C-V) behavior of the metal/Bi2Ti 2O7/n-Si metal-oxide-semiconductor (MOS) structure has been studied. The analyses of C-V curves show that a high builtin voltage of 11 V on Si can be achieved by bias-temperature (BT) process. The hysteresis loops in C-V curves of the MOS structure were also observed clearly. From the dependence of C-V properties on different BT processes, it is deduced that the hysteresis loops are dominated by the mobile negative charges in the oxide.
