一、課程說明(Course Description)
This course focuses on the basic physics of semiconductors, in particular
the various quantum processes that are important for device applications.
The highlights are band structures, electron-
impurity scattering, optical transitions, and electron transport theory.

The students are required to have backgrounds in quantum mechanics and
solid state physics both at the introductory level.
