Resumen:

The dependence with the measurement frequency observed in the Capacitance-Voltage characteristics of Metal-Insulator-Semiconductor structures using an amorphous oxide semiconductor material is presented and analyzed. It is demonstrated by simulation that the effect is due to the Distribution of States (DOS) present in the energy gap of the semiconductor material and strongly depends on the capture cross section of the DOS. © 2015 IEEE.
