Abstract
- An Ni/Au Schottky contact on an AlGaN/GaN heterostructure has been prepared. By using the peak-conductance model, the threshold voltage and the series resistance of the AlGaN/GaN diode are simultaneously extracted from the conductance—voltage (G—V) curve and found to be in good agreement with the ones obtained by using the capacitance—voltage (C—V) curve integration and the plot of dV/d(ln I) versus current I. Thus, a method of directly and simultaneously extracting both the threshold voltage and the series resistance from the conductance—voltage curve for the AlGaN/GaN Schottky diode is developed.
