Question 10. Write program for plotting the ideal high-frequency capacitance voltage plot.

    As mentioned above, there is a small number of negative charges in oxide, which need extra voltage to neutralize to reach the same capacitance according to the equation:

    According to the previous task, the differences between ideal value and real value can be calculated in flat-band and mid-gap conditions.

    As shown above, the two voltage difference are almost same. In fact, there do exist a constant voltage difference between ideal and real values at same capacitance.
