By completing the Drift-Diffusion Lab in ABACUS - Assembly of Basic Applications for Coordinated Understanding of Semiconductors, users will be able to: a) understand the phenomenon of drift and diffusion, b) physically and mathematically describe the basic drift and diffusion mechanisms, and c) perform light excitation experiments on a semiconductor bar.


The specific objectives of the Drift-Diffusion Lab are:
