|Special Subject for Teacher Education
|Many advanced problems in the fields of electrical, computer and systems engineering relate to the electronics based of the electronic properties of solids. Therefore, the understanding ot the electronic properties is one of the important elements to solve the problems in these fields.|
In this course, students will learn the fundamentals of Statistical Mechanics and Thermodynamics necessary to understand the electoronic properties of solids, and learn the basics of how to deal with various problems relating to electrons.
