On the propagation of nonlinear solitary waves in a distributed Schottky barrier diode transmission line

A nonlinear distributed Schottky barrier diode is analyzed and it is found to be similar to a 3-component quasi-neutral plasma consisting of negative ions and electrons that are neutralized with positive ions. In such a plasma, it has been shown that both KdV and mKdV solitons can exist. We obtain the criteria for the distributed Schottky barrier diode that will permit the propagation of both KdV and mKdV solitary waves.
