Ansys Lumerical CHARGE

This learning track introduces the Ansys Lumerical CHARGE solver which can be used for electrical simulation of semiconductor devices inside the finite-element multiphysics environment. We first discuss the different types of simulations supported by the solver. Following this, we demonstrate the application of the CHARGE solver for steady-state analysis of a simple p-n junction diode. We then discuss various material models used by the CHARGE solver for electrical simulation. This is followed by a discussion of the various simulation objects available in the CHARGE solver such as doping profiles, sources, monitors etc. Finally, we discuss the small-signal AC and transient (time-dependent) simulation mode that the CHARGE solver is capable of.



This course introduces the Ansys Lumerical CHARGE solver which can be used for electrical simulation of semiconductor devices inside the finite-element multiphysics environment. A brief description of the solver physics, the different types of simulations supported by the solver, and some real-world application examples for which the CHARGE solver can be used will be also discussed.

In this course, we will demonstrate the application of the Ansys Lumerical CHARGE solver for steady-state analysis of a simple p-n junction diode. This is a basic example of how the CHARGE solver can be used for electrical analysis of a simple system. We will walk you through the workflow of the simulation including how to set up, run, and analyze the results of the simulation. You will also get familiar with the main parts of the Finite Element IDE user interface.

This course contains useful information about various material models used by the Ansys Lumerical CHARGE solver for electrical simulation. You will also get to know the material database which contains the electrical properties of commonly used materials.

In this course, various simulation objects available in the CHARGE solver such as doping profiles, sources, monitors, and boundary conditions are introduced and the different settings required to set up these objects are briefly reviewed. Also, a number of tips for efficient geometry setup in the Finite Element IDE design environment are provided.

The "My First Simulation" course of the CHARGE Learning Track includes a steady-state simulation performed by the CHARGE solver. This course introduces basic examples of other simulation modes that the CHARGE solver is capable of, including the small-signal AC and transient (time-dependent) simulation modes. It also contains a hands-on demo of small-signal AC and transient simulations of a simple p-i-n diode.
