To visualize the distribution, on the Study toolbar, click
Get Initial Value (
). Then add a plot group and display the corresponding dopant density. The signed doping concentration,
semi.Nd-semi.Na (positive for net donor doping and negative for net acceptor doping), gives the net doping and can be useful for visualizing the effect of different doping steps. If multiple doping features are superimposed, it is possible to visualize the total dopant concentration or to display the contribution from individual doping features.
The semi.Nd-semi.Na expression shows the total net doping due to the sum of all doping features. To see the distribution from a single doping feature the corresponding node tag must be included in the plot variable.
The node tags are shown in curly brackets next to the nodes in the Model Builder. Analytic Doping Model features are tagged as
adm# and
Geometric Doping Model features are tagged as
gdm#, where
# corresponds to the number of the feature. The dopant concentration from each doping feature is available as
semi.<tag>.Na for acceptor doping or
semi.<tag>.Nd for donor doping. For example,
semi.adm1.Nd for a donor distribution from the first
Analytic Doping Model added to the component.
