What Can the Semiconductor Module Do?
The Semiconductor Module is a collection of interfaces and predefined models for COMSOL Multiphysics, which can be used to model semiconductor devices.
It includes a dedicated physics interface to model semiconductor devices with the drift–diffusion equations, enhanced capabilities for modeling electrostatics, and an Electrical Circuits interface (with a SPICE import facility) that can be coupled to the device level models.
To include the effect of quantum confinement in the conventional drift–diffusion equations, the computationally efficient density-gradient formulation is available.
The Semiconductor Module also provides dedicated interfaces to solve the single-particle Schrödinger Equation and Schrödinger–Poisson Equation, for general quantum mechanical problems as well as quantum-confined systems such as quantum wells, wires, and dots.
The included Application Library contains a suite of examples that demonstrate how to use the physics interfaces for modeling a range of practical devices. These models provide step-by-step instructions demonstrating how to use the physics interface to model practical devices.
The Semiconductor Module is well documented and includes a detailed outline of the underlying theory on which it is based. The software is uniquely transparent because the model equations are always visible. Furthermore, you have complete freedom to include phenomena that are not predefined in the Module with easy-to-enter user-defined expressions and equations.
