3D Analysis of a Bipolar Transistor

Application ID: 19699

This model shows how to set up a 3D simulation of a n-p-n bipolar transistor. It is a 3D version of the device shown in the Bipolar Transistor model, and demonstrates how to extend semiconductor modeling into 3D using COMSOL Multiphysics.

As in the 2D version of this model, the device is simulated whilst operating in the common-emitter regime. A voltage driven study is computed to characterize the current-voltage response of the device, and a current driven study is performed to simulate the device operating as an analog current amplifier.

This model example illustrates applications of this type that would nominally be built using the following products:
