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.
