一、課程說明(Course Desc<x>ription)
<br>This course focuses on the basic physics of semiconductors, in particular
<br>the various quantum processes that are important for device applications.
<br>The highlights are band structures, electron-
<br>impurity scattering, optical transitions, and electron transport theory.
<br>
<br>The students are required to have backgrounds in quantum mechanics and
<br>solid state physics both at the introductory level.
