Abstract
The electrical and interfacial properties of Ta2O5/ZnO/p-Si metal-insulator-semiconductor structures are investigated using high frequency capacitance-voltage and conductance-voltage characteristics. Charge trapping behaviour under Fowler-Nordheim constant current stressing is also reported. An interface state density (1.22 × 1012 cm-2 eV-1) has been observed for the Ta2O5/ZnO interface.
