Semiconductor Device Simulation with MATLABTM

The purpose of this project is to develop a functional semiconductor device simulator that is modular
in nature in order to allow for flexibility during programming and to allow for future development with
relative ease. In addition, the program’s main goal is to provide a tool that can supplement device
modeling and the standard course material covered in a basic college level introduction,
semiconductor device physics, course or and numerical analysis course and to construct basic PN
semiconductor devices which can be studied using standard numerical analysis techniques. A device
modeling program is developed using the basic MATLAB tools necessary to understand the operation
of the program and allow future developments as necessary. MATLAB’s capability and inherent
nature of handling matrices and matrix operations makes this approach an excellent technique to
develop numerical analysis algorithms.
The program solution will be used to examine device parameters such as carrier statistics, device
potential, and internal electric fields. The device solution is compared to analytical approximations in
order to further strengthen the understanding between theory and exact numerical solutions and how
those solutions are obtained.
