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.
