A modified Norde function for the measurement of the series resistance and the voltage-dependent barrier height of triangular barrier diodes

The Norde function [J. Appl. Phys. 50, 5052 (1979)] used for measuring the barrier height, series resistance, and ideality factor of a Schottky barrier diode has been modified to obtain the same parameters for a triangular barrier diode (TBD). Unlike Schottky barrier diodes, the barrier height of a TBD depends upon the applied voltage and changes linearly with it. In order to calculate the additive term in the TBD barrier height, the modified function is therefore plotted for both reverse and forward bias cases. It is shown later that the modified Norde function enhances the accuracy of the results.
