The Electrode node is a subfeature for modeling what happens when a dielectric is in contact with a metal surface. Note that the electrode domain needs to be excluded from the computation domains.

Specify the terminal properties. To indicate which boundaries belong to the same terminal, enter the same name in the Terminal field.

Select a Terminal type — Voltage (the default) or Circuit:

This section is available only when the Material model of its parent feature is Charge transport. It is used to specify boundary conditions for charge carriers at the metal surface. Available boundary conditions are No diffusive flux (the default), Number density, Open boundary, No flux, Flux, and Surface emission (for electrons and holes).

This section is available only when the boundary condition of electrons or holes is set to Surface emission. Depending on the parent feature, different surface emission mechanisms are available.

Generally, carriers drift inward to the boundary conditions. For outward-drifting carriers, two options, Open boundary and No flux, are available.
