Results parameters

Voltage, current and power

These results parameters give you access to the voltage, current and power for the base and collector contacts, and for the internal shunt elements. The values displayed in the batch results will be the steady-state values (for steady state excitation mode) or the final transient time step (for transient excitation).

Spatial results

These parameters give you access to all of the results used by the spatial graphs . You must specify the distance from front (in um) in parentheses after the name. e.g. Jn(10.5) gives the electron current density at the point 10.5 um from the front surface. The values displayed in the batch results will be the steady-state values (for steady state excitation mode) or the final transient time step (for transient excitation).
