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:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Grille de Spécifications and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
