Abstract
A new method is presented to extract the junction parameters from current–voltage characteristics of Schottky junctions exhibiting high leakage or other excess currents at low bias and current levels, for reduction of errors and uncertainity of the evaluation. In contrary to the Richardson plot, using the new method presented here, the Schottky junction parameters are evaluated from the measured experimental points directly instead of the extrapolated values of saturation current. The temperature dependence of forward bias, which is necessary for a given thermionic emission current level, is used. After transformation of the data, a linear plot is obtained, which yields both the barrier height and effective Richardson constant.
