Every software package contains a full set of examples suitable for that version and are installed with the software. If you see examples here that are not in your installation you should consider updating to a later version of the software. These examples can be used by beginners and advanced users for product evaluation, teaching purposes, and self-training.

This example demonstrates:
-QT MESH statement.
-BBT.NONLOCAL and BBT.NLDERIVS commands.
In this example, the QT MESH statement is used to set up a mesh suitable for tunnelling calculations. The device is a degenerately doped silicon p-n diode. Non-local Band-To-Band tunnelling is selected on the MODELS statement by using the BBT.NONLOCAL keyword. Because the solution will go to relatively high levels of tunnelling current, convergence may become difficult. The optional parameter BBT.NLDERIVS is used to improve this. The diode is biased into both forward and reverse biases. In forward bias a tunnelling current occurs up to about 0.3 V, and at higher bias the usual forward bias diffusion current occurs as can be seen in the LOG file.
