Abstract:

AbstractThe capacitance of a Schottky barrier diode is evaluated considering the effects of deep-level impurities and the series resistance of the device. Because of the series resistance, the forward capacitance-voltage characteristics of the diode exhibit a peak. It is found that deep levels have a significant effect on the capacitance peak. The capacitance peak increases with increasing density of deep levels and decreasing value of the activation energy of the levels.
