Abstract

This paper is concerned with the computation of semiconductor device current-voltage characteristics. We describe an algorithm which allows the computation of characteristics by continuation in a parameter which approximates the arc length of the characteristic. The use of this parameterization allows the characteristic to continue beyond snap-back voltages, while continuation in the voltage fails past snap-back voltages. We discuss the implementation of the parameterization and give a numerical example.
