Course description and aims

Properties of electrons in solids are the basis of all the electronic materials and electron devices. This course provides fundamental treatment to understand the electron's behaviors in solids based on the solid state physics.
Beginning with a brief review of fundamental quantum mechanics, some perturbation theories will be lectured to understand electron states in various potentials where the analytical solution of Schrodinger equation is hard to be obtained.
In order to treat electrons in solids, the electrons should be regarded as waves. We will see that carrier electrons can be treated as waves which propagate in the solids, and which cause scattering and diffraction. Furthermore, it is recognized that energy bands will be formed in a periodic potential of solids, which is the basis for carrier transport in metals and semiconductors.
  This course also covers band theories of solids based on nearly-free-electron approach with a periodic perturbation potential and more precise tight binding theory. The concepts of Brillouin zone, Bloch theorem, empty lattice approximation, and chemical bonds in solids are introduced as a basis for the band theories. Then, students will gain an understanding of the nearly-free-electron approach using the perturbation theory and the tight binding theory of solid. In particular, students learn the calculation methodology of the band structures of diamond and zinc-blend semiconductors.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
