Introduction to the Semiconductor Module

In Part 1 of this course on semiconductor modeling using COMSOL Multiphysics^® and the Semiconductor Module, we begin by highlighting the physics interfaces available and discuss some of the fundamentals of semiconductor modeling, including equations and key assumptions. We then demonstrate using COMSOL Multiphysics^® for modeling metal contacts and doping by walking you though the model-building process from start to finish using the Schottky Diode tutorial model.  When metal is brought in contact with a semiconductor, a potential barrier forms at the contact point as a result of the work function difference.  In this "ideal" model, we assume that the effects of surface states, image force lowering, tunneling, and diffusion effects are negligible when computing the current transfer between the semiconductor and metal at the interface. Following this, we will cover discretization and meshing strategies to improve convergence in semiconductor models.
